For a guide to many of the web 2.0 sites out there, check out the go2web2.0 application and tools directory. It’s an overwhelming list but an interesting browse. Unfortunately there is no real indicator that separates out the relevant and “must know about” from the obscure. For example, in the social category: digg is lumped with a bunch of other sites I have never heard of. The lesser known sites tend to be very niche focused (for example: steepster – tea drinkers unite)
If you click through the site icon, there is a short description and you can get a sense of the buzz about the site, as tweets, blogs and youtube videos that reference the web2.0 site are displayed. If you are willing to spend a bit of time, you can discover all sorts of interesting sites.
