I think the whole web 2.0 thing is great but not everyone knows what a web 2.0 site is or where to find it. Web 2.0 is the future of the internet and it’s here.
These are sites like fackbook, flickr, meebo, Digg, and many more. All of these sites are great but can be hard to find.
Here is a great web 2.0 directory.
Also, I’ve found this post explaining some of the new web 2.0 sites.
