Binary gender radio button on new "Common Knowledge" section

Tim says on his blog post that ...yes, we can discuss the whole radio-buttons-for-gender topic. See here, here. I'm of the opinion that two genders plus maybe "unknown" and "n/a" (for Nyarlathotep?) are the best you can get without consensus-splitting disagreement.

I really think this is well-meaning uninformedness, rather than a deliberate attempt to be exclusionary, so please be nice if you go discuss it there (which is certainly more likely to produce results than discussing it here where Tim will never see it.)

(Edited to fix link to blog post).

i've started a thread here:

please chime in! there's general consensus that male/female doesn't work for a number of reasons, but i don't know how great i feel about the options being male, female, n/a, or "other."
