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).
