Ch 10: The Impact of Web 2.0 on Communities

  (Suggested Vignette – Craig Newmark (Craig’s List) Zack Rosen (CivicSpaceLabs))

"Network effects from user contributions are the key to market dominance in the Web 2.0 era." (Tim O'Reilly). Collective intelligence, frequently harnessed in communities of people, is the essence of web 2.0. Note: this chapter will build on many of the ideas that Tim introduced in the "What is Web 2.0" paper.

Architecture of Participation

"Web 2.0 companies set inclusive defaults for aggregating user data and building value as a side-effect of ordinary use of the application." (Tim O'Reilly) Web 2.0 companies build their products with the idea that user contribution will improve the overall solution. As users add content to a web 2.0 site, they make the site even more valuable, and this effect increases as more and more users contribute to the community. Communities and contribution form around discussion threads facilitated by feeds and services like Technorati, Feedster, and TechMeme that highlight the topics that others are talking about in addition to tracking links back to content (may reference We the Media p 41-42). We may want to mention the Cult of the Amateur.

Wisdom of Crowds

With the emergence of web 2.0, online communities are beginning to morph. More user communities are emerging to create dynamic content via wikis, blogging, podcasts, tagging, etc. This builds on what open source communities have known about the wisdom of crowds and user / developer participation ("given enough eyeballs all bugs are shallow") with a shift from static, passive content to dynamic, user created, collective content. Crowd mentality also takes over to create interesting trends like the cameratoss and whatsinyourbag tags in Flickr that have inspired hundreds of people to toss their cameras and photograph everything in their bags to post them online.
