Yes today the biggest social networking site Facebook completes 7 years of existence since its launch in 2004. So much has changed since I first joined in 2007, when not much famous and the real essence wasn't yet achieved. But today everything is different. Changing drastically the way we socialize online and being such a powerful medium for connection. 1/4th of the people having access to Internet are part of it. Well this is one of those things which doesn't need much of an explanation ;)Edit: Check out some fun and cool facts of facebook in one of my earlier posts here
Happy 7th b'day facebook!
