Can I just say how much I love this "Tech Diversity Bingo Card" that was posted on Geek Feminism recently: http://www.maleallies.com/ The website is "Male Allies" but the bingo card is designed to be applicable to allies of any historically marginalized group in tech. I also like that -- unlike many other "bingo card" social commentaries -- it highlights things that allies can do right rather than what's often done wrong (yay positive behavior modeling).
