I just wanted to tell you how excited I am about the Social Networking Directory! It has to be the biggest Web 2.0 resource out there. I mean I'm sitting here going through it and can't believe how many social sites there are!
There are over 3,000 sites in the Social Networking Directory. The best thing though... is that they ALL have a description about what the site actually does! I mean I've seen the books where people just give you links... but the Social Networking Directory not only gives you the description of each site, it has the graphic, tags, and the link!
I would like to recommend that you go and get it right now! It is Free!
