I really liked today's "conversation" in the Washington Post, "How to be black" Baratunde Thurston. He's a comedian and writer, and wrote an auto-biographical book, some of which is excerpted in a slideshow on the WP website.
Worth a look. I really loved #11 "How to speak for all black people", and #13 "How to be the black employee", because I think they are also applicable to being a woman or other underrepresented person in technology. (I think I had a post on this?.... ah, yes, I did.)
