Web 2.0 is a term often applied to a perceived ongoing transition of the World Wide Web from a collection of websites to a full-fledged computing platform serving web applications to end users. Ultimately Web 2.0 services are expected to replace desktop computing applications for many purposes. [|en.wikipedia.org/wiki/Web_2.0]

Wikipedia, an online encyclopedia based on the unlikely notion that an entry can be added by any web user, and edited by any other, is a radical experiment in trust One of the things that has made a difference is a technology called [|RSS]. RSS is the most significant advance in the fundamental architecture of the web since early hackers realized that CGI could be used to create database-backed websites. RSS allows someone to link not just to a page, but to subscribe to it, with notification every time that page changes. Skrenta calls this "the incremental web." Others call it the "live web". In exploring the seven principles above, we've highlighted some of the principal features of Web 2.0. Each of the examples we've explored demonstrates one or more of those key principles, but may miss others. Let's close, therefore, by summarizing what we believe to be the core competencies of Web 2.0 companies: Services, not packaged software, with cost-effective scalability Control over unique, hard-to-recreate data sources that get richer as more people use them Trusting users as co-developers Harnessing collective intelligence Leveraging the long tail through customer self-service Software above the level of a single device Lightweight user interfaces, development models, AND business models The next time a company claims that it's "Web 2.0," test their features against the list above. The more points they score, the more they are worthy of the name. Remember, though, that excellence in one area may be more telling than some small steps in all seven.
