7.6 Other Key Web 2.0 Terms and Concepts

Learning Objectives

After studying this section you should be able to do the following:

  1. Know key terms related to social media, peer production, and Web 2.0, including RSS, folksonomies, mash-ups, location-based services, virtual worlds, and rich media.
  2. Provide examples of the effective business use of these terms and technologies.

RSS

RSS (an acronym that stands for both “really simple syndication” and “rich site summary”) enables busy users to scan the headlines of newly available content and click on an item’s title to view items of interest, thus sparing them from having to continually visit sites to find out what’s new. Users begin by subscribing to an RSS feed for a Web site, blog, podcast, or other data source. The title or headline of any new content will then show up in an RSS reader. Subscribe to the New York Times Technology news feed, for example, and you will regularly receive headlines of tech news from the Times. Viewing an article of interest is as easy as clicking the title you like. Subscribing is often as easy as clicking on the RSS icon appearing on the home page of a Web site of interest.

Many firms use RSS feeds as a way to mange information overload, opting to distribute content via feed rather than e-mail. Some even distribute corporate reports via RSS. RSS readers are offered by third-party Web sites such as Google and Yahoo! and they have been incorporated into all popular browsers and most e-mail programs. Most blogging platforms provide a mechanism for bloggers to automatically publish a feed when each new post becomes available. Google’s FeedBurner is the largest publisher of RSS blog feeds, and offers features to distribute content via e-mail as well.

Folksonomies

Folksonomies (sometimes referred to as social tagging) are keyword-based classification systems created by user communities as they generate and review content. (The label is meant to refer to a people-powered taxonomy.) Bookmarking site Del.icio.us, photo-sharing site Flickr (both owned by Yahoo!), and Twitter’s hash tags all make heavy use of folksonomies.

With this approach, classification schemes emerge from the people most likely to understand them—the users. By leveraging the collective power of the community to identify and classify content, objects on the Internet become easier to locate, and content carries a degree of recommendation and endorsement.

Flickr cofounder Stewart Butterfield describes the spirit of folksonomies, saying, “The job of tags isn’t to organize all the world’s information into tidy categories, it’s to add value to the giant piles of data that are already out there” (Terdiman, 2005). The Guggenheim Museum in New York City and the San Francisco Museum of Modern Art, among other museums, are taking a folksonomic approach to their online collections, allowing user-generated categories to supplement the specialized lexicon of curators. Amazon.com has introduced a system that allows readers to classify books, and most blog posts and wiki pages allow for social tagging, oftentimes with hot topics indexed and accessible via a “tag cloud” in the page’s sidebar.

Mash-up

Mash-ups are combinations of two or more technologies or data feeds into a single, integrated tool. Some of the best known mash-ups leverage Google’s mapping tools. HousingMaps.com combines Craigslist.org listings with Google Maps for a map-based display for apartment hunters. IBM linked together job feeds and Google Maps to create a job-seeker service for victims of Hurricane Katrina. SimplyHired links job listings with Google Maps, LinkedIn listings, and salary data from PayScale.com. And Salesforce.com has tools that allow data from its customer relationship management (CRM) system to be combined with data feeds and maps from third parties.

Mash-ups are made easy by a tagging system called XML (for extensible markup language). Site owners publish the parameters of XML data feeds that a service can accept or offer (e.g., an address, price, product descriptions, images). Other developers are free to leverage these public feeds using application programming interfaces (APIs), published instructions on how to make programs call one another, to share data, or to perform tasks. Using APIs and XML, mash-up authors smoosh together seemingly unrelated data sources and services in new and novel ways. Lightweight, browser-friendly software technologies like Ajax and HTML5 can often make a Web site interface as rich as a desktop application, and rapid deployment frameworks like Ruby on Rails will enable and accelerate mash-up creation and deployment.

Location-Based Services

Computing devices increasingly know where you are—and this is creating all sorts of new opportunities for social media. Twitter, Facebook, and Google Buzz are among the many social services that have added location-based options, allowing you to tweet or post a status update attached with a physical location as determined by your phone’s global positioning system (GPS), triangulation from nearby cell phone towers, or proximity to neighboring Wi-Fi hotspots. This introduces a whole new way to gather and share information. In a new part of town and curious what folks are saying about the spot? Search for tweets tagged as being posted around that location.

Augmented-reality apps can overlay real data on top of images from a GPS and compass-equipped smartphone. Swivel your iPhone around with Stella Artois’s Bar Finder app open, and it’ll point you to the nearest Stella-equipped watering hole (it’ll also let you text your friends to join you for a drink and call a cab for a safe ride home). Wikitude overlays images appearing through your phone’s camera lens with geotagged data from Wikipedia. Point your Yelp app down the street and activate the monocle feature to see starred reviews hover over the top of establishments that appear on screen.

Boston-based SCVNGR (pronounced “scavenger”), a gaming app, has allowed over four hundred clients, including Princeton, MetLife, and Boston’s Museum of Fine Arts, to create their own mobile phone-based scavenger hunts. The profitable firm has a 90 percent client return rate and had attracted funding from Google Ventures and Highland Capital Partners all before founder Seth Priebatsch turned twenty-one (Kincaid, 2009).

Perhaps the best known among the location-based pure plays is Foursquare. The service allows players to “check in” at different locations, allowing players to earn “badges” displayed in the app for completing specific achievements (“gym rat” for exercise buffs, “school night” for weeknight bar hoppers). Check into a location more than anyone else and you become that spot’s “mayor.” Foursquare users can follow public location postings from their friends, discovering when someone’s close by and gaining recommendations on new places to explore. Foursquare grew to over one million users roughly one year after the service debuted at the 2009 South by Southwest conference. Firms are now using Foursquare for promotions and to support loyalty programs—offering “mayor specials” or sending out coupons and other incentives when users are nearby. Starbucks, the Bravo television channel, frozen yogurt chain Tasti D-Lite, and the Milwaukee-based burger chain AJ Bombers are among the diverse clients leveraging the service.

Of course, all this public location sharing raises privacy concerns. The Web site PleaseRobMe.com was created to draw attention to the potentially dangerous issues around real-time location sharing. After a brief demonstration period, the site stopped its real-time aggregation of publicly accessible user-location data and now serves as an awareness site warning of the “stalkerish” side of location-based apps. In most cases, though, users remain firmly in control—determining if they want to keep a visit private or release their locale to verified “app friends” or to the broader online space.

Virtual Worlds

In virtual worlds, users appear in a computer-generated environment in the form of an avatar, or animated character. Users can customize the look of their avatar, interact with others by typing or voice chat, and can travel about the virtual world by flying, teleporting, or more conventional means.

The most popular general-purpose virtual world is Second Life by Linden Labs, although many others exist. Most are free, although game-oriented worlds, such as World of Warcarft (with ten million active subscribers), charge a fee. Many corporations and organizations have established virtual outposts by purchasing “land” in the world of Second Life, while still others have contracted with networks to create their own, independent virtual worlds.

Most organizations have struggled to commercialize these Second Life forays, but activity has been wide-ranging in its experimentation. Reuters temporarily “stationed” a reporter in Second Life, presidential candidates have made appearances in the virtual world, organizations ranging from Sun Microsystems to Armani have set up virtual storefronts, and there’s a significant amount of virtual mayhem. Second Life “terrorists” have “bombed” virtual outposts run by several organizations, including ABC News, American Apparel, and Reebok.

Even grade schoolers are heavy virtual world users. Many elementary school students get their first taste of the Web through Webkinz, an online world that allows for an animated accompaniment with each of the firm’s plush toys. Webkinz’s parent company, privately held Ganz, doesn’t release financial figures. But according to Compete.com, by the end of 2008 Webkinz.com had roughly the same number of unique visitors as FoxNews.com. The kiddie set virtual world market is considered so lucrative that Disney acquired ClubPenguin for $350 million with agreements to pay another potential three hundred fifty million if the effort hits growth incentives (Barnes, 2007).

YouTube, Podcasting, and Rich Media

Blogs, wikis, and social networks not only enable sharing text and photos, they also allow for the creation and distribution of audio and video. Podcasts are digital audio files (some also incorporate video), provided as a series of programs. Podcasts range from a sort of media blog, archives of traditional radio and television programs, and regular offerings of original online content. While the term podcast derives from Apple’s wildly successful iPod, podcasts can be recorded in audio formats such as MP3 that can be played on most portable media players. (In perhaps the ultimate concession to the market leader, even the iPod rival Microsoft Zune refers to serialized audio files as podcasts on its navigation menu).

There are many podcast directories, but Apple’s iTunes is by far the largest. Anyone who wants to make a podcast available on iTunes can do so for free. A podcast publisher simply records an audio file, uploads the file to a blog or other hosting server, then sends the RSS feed to Apple (copyrighted material cannot be used without permission, with violators risking banishment from iTunes). Files are discovered in the search feature of the iTunes music store, and listings seamlessly connect the user with the server hosting the podcast. This path creates the illusion that Apple serves the file even though it resides on a publisher’s servers.

While blogs have made stars of some unknowns, the most popular podcasts are from mainstream media outlets. A recent visit to the podcasting section of iTunes showed that eight of the top ten most popular podcasts were high-quality productions of mainstream media programs, including offerings from CBS, Comedy Central, NPR, and PBS. Podcasts are also revolutionizing education, with scores of universities “open sourcing” their classrooms and offering lectures for public consumption via Apple’s iTunesU.

In contrast to iTunes, YouTube actually hosts video on its own servers, so all you need to do is shoot a video and upload it to the site. YouTube is a bastion of amateur video, with most clips shot and uploaded by nonprofessionals. It’s also become a protest site (e.g., “A Comcast Technician Sleeping on my Couch”). However, YouTube has also become a go-to distribution platform for professional content such as ad clips, customer support guides, music videos, TV shows, movies, and more. Much of this rich media content can be distributed or streamed within another Web site, blog, or social network profile.

Key Takeaways

  • RSS fosters the rapid sharing and scanning of information, including updates from Web 2.0 services such as blogs, wikis, and social networks. RSS feeds can be received via Web browsers, e-mail, cell phones, and special RSS readers.
  • Folksonomies allow users to collaboratively tag and curate online media, making it easy for others to find useful content. Since folksonomies are created by users themselves, they are often more easily understood and embraced than classification schemes imposed by site owners.
  • Mash-ups promote the useful combination of different Web services, such as maps and other information feeds. Mash-up authors leverage technologies such as APIs and XML to combine seemingly unrelated data sources and services in new and novel ways.
  • Location-based services are increasingly combining geolocated data with social media. Users can now quickly see related social media surrounding an area, even overlaying this data on top of maps and images through a phone’s camera lens. Sites like Foursquare are morphing into loyalty and customer-rewards programs. While users are largely in control of sharing location data, some fear privacy and security issues from oversharing.
  • Virtual worlds allow users to interact with and within a computer-generated alternate reality.
  • Internet media is increasingly becoming “richer,” leveraging audio, video, and animation. Organizations and users are creating and distributing rich media online, with interesting content spreading virally.

Questions and Exercises

  1. What is RSS and an RSS reader? Why would an individual use one? Why would a firm use RSS?
  2. Use an RSS reader like Google Reader, or the features built into your e-mail program or browser, and subscribe to RSS feeds. Discuss your experience with the class. Which feeds did you subscribe to? What did you like or not like about using an RSS reader?
  3. If you have a smartphone, download Foursquare or other location-based app. Is this service popular in your community? Research how firms are leveraging these tools for real business value.
  4. Investigate SCVNGR. Many schools are using the tool for orientation programs. Is your school using this? If so, participate in a SCVNGR game on campus. If not, build a case for considering SCVNGR (or similar service) and share this with your student government or student orientation office.
  5. Are privacy concerns from location-based apps valid? What can users do to be safe even while using location-based apps?
  6. Visit Second Life or another virtual world. Create an avatar and look for examples of corporate/commercial involvement. Be prepared to discuss your experience—both positive and negative.
  7. Investigate some of the many virtual worlds targeted at children, including Webkinz, Club Penguin, and Whyville. What are the revenue models for these efforts? How do these sites ensure they are safe for children? Assume the role of a parent—what are the pros and cons of these sites? Which (if any) would you allow your children to participate in? Why? Would you invest in any of these efforts or advise corporations to enter the kid-focused virtual world space? Why or why not?
  8. If you don’t already own it, download iTunes for free, go to the iTunes music store, and explore the free podcast section. Alternatively, find podcasts from another service. Which podcasts seem to be the most popular? Why? Do you use podcasts or other rich media? Why or why not?
  9. Visit YouTube. Identify examples of corporations using the service. Identify examples of customer use. Be prepared to discuss your findings with the class. Do you think Google is making much money with YouTube? Why or why not?
  10. Which firm do you think spends more on the technology infrastructure that powers its service—Apple with iTunes podcasts or Google with YouTube? Explain your answer.
  11. Why would a firm make its data available via XML to use as a mash-up? What can it gain? Are there any risks involved in providing programming hooks that allow the creation of mash-ups?
  12. Give examples of efforts that take advantage of folksonomies. Why are folksonomies considered to be useful?
  13. Do you spend time in rich media Web sites? Which ones? How much time do you or your friends spend on these sites? How would you describe the quality of rich media content found online?
  14. How might a firm use rich media online? What concerns does a firm or individual face with respect to rich media?
  15. Why do you suppose that the most popular podcasts come from established media firms (e.g., Comedy Central, NPR) rather than amateurs, while the top bloggers emerged outside the professional journalist/writer community?
