Web 2.0 Trends

Web 2.0 is actually a phrase coined by O'Reilly Media in 2004. As most other definitions, Web 2.0 doesn't have a hard boundary

On September 30, 2005, Tim O'Reilly wrote a piece summarizing the subject. The mind-map pictured above (constructed by Markus Angermeier on November 11, 2005) sums up the memes of Web 2.0, with example-sites and services attached (See the above picture).
