Try it

 

Well, I appreciate the effort, but I really didn't want a list of sites, I wanted to target specific niches.
Which is something nobody has been able to come up with, so I reckon there's a gap in the market here - if anyone wants to start up a technorati type of directory for social media, it seems like there's potential for it.

 

I don't know any directory but wikipedia has a good lists with a short descriptions for each network:
