>Secondly, do you think that "other" is enough? To what lengths should developers go to handle rare corner cases? Other is enough. It covers all the possible alternate cases. If the person really doesn't identify with either gender, they can select it. If they don't want it to be public, it's broad enough that selecting it doesn't reflect anything on the person, especially if they post pictures(like several people in the "other" camp do in the comments have). Randall even admitted in his blog post that it's simply not worth the effort to cover all the possible cases. The problem with this entire thing is that it's so complicated. The original survey apparently wasn't good enough for a segment of the population, and the question was framed for pure genetics. You're damned if you do and damned if you don't, because you'll get complaints no matter what you do.
