We could've probably normalized this data better. The fact of the matter is that guys use foursquare nearly twice as much as girls do, so every venue will have dramatically more guy check-ins. A 7% male edge actually makes it one of the more female venues in the city.
Now I'm confused. Your post implies that this is a raw excess (truly 7% more men than women, which is a relative excess of women compared to the citywide average of 2 male:1 female checkin), right? But shasha...sha's post indicates that you've actually already normalized, which would imply that this is actually 7% more men than average, which is already quite male (2 male per 1 female, per shasha...sha's post).
