1) i took a comment (

http://www.hackerfactor.com/GenderGuesser.html which came up on this thread:

2) I would surmise that the point of lists like these are to raise awareness of injustices or slights that are done, particularly ones that others may not be aware of, because they are not subjected to them.
3) You're a member of the community, can you really not think of anything you could do to make things different? Why not do something that bucks the geek/nerd stereotype? Why not help someone else do it? Why not encourage/help someone who's not a stereotypical nerd into the field? Why not just object to stereotyping of programmers?
These aren't problems that are going to change immediately. Being reminded that there are still problems isn't a bad thing imo. Just as being reminded that people do care about the issue, and would like to make things different (as you have done).
So the problem has been recognized. There is a will to do something about it. Let's do something. There are organizations like RailsBridge that are forming ( http://railsbridge.org/ ). The ACM-W exists ( http://women.acm.org/ ).
If you want things to be different, pick something to do and do it.
