I actually ran this experiment already for a dating app concept, using
some established research on gender detection based on writing
(against at least 10-20 tweets) combined with a database of female
names for user names. I also tried running this on an ANN but that
wasn't fruitful and required me to build a custom application to plunk
through piles of public timeline users "verifying" genderness.

But yes, it's possible and yes, it works pretty well, especially if
the user filled in their profile and has a decent number of updates.
