The Women of Web 2.0?

So I'm walking through my RSS feed list and with the exception of danah, its rather male dominated (and white male, at that...well, I think so...  I'm really not sure in all cases, to be honest).   

Does anyone have a few recommendations to help me out with a more balanced perspective?  Female or minority entrepreneurs, academics, etc. in and around the technology services space, specifically around identity, personal information management, user interface, etc?
