That "probably" there isn't justified, in my opinion. As others in that FAQ thread have pointed out, StackOverflow isn't a place where a lot of third-person interaction is taking place, so I'd consider it a stretch to make that out as a reason that non-males are lacking there.

Maybe it's just that women often have better things to do than to ask strangers for help on why their Haskell state monad is acting up.
