Today I was searching the web to gather statistics about Web 2.0 applications. Im interested to know the number of web 2.0 applications or services in the web . I started with google of course , one interesting link I came across is : Web 2.0 Summit . This website gathers keynotes and experts in technology and web 2.0. Unfortunately I couldn’t find what Im looking for that is the number of web 2.0 services. I then toke a look at Feedmyapp which is a very popular website that hosts a huge directory of web 2.0 tools ,a good database I have used many times. Feedmyapp lists 7461 sites , but I think there are more than that . I knew that because I have seen many tools that are not listed in feedmyapp. Its interesting to know how many web 2.0 applications are out there in the internet. If you know the answer or any link that gives this information ,I would be grateful. This research is only the beginning and Im still working on it.
