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.

Does foursquare publish male/female ratio user base stats? Based on the people I know, it seems like only males use apps like foursquare.

It may be the "early adopter" effect. In some cases, over 95% of (self-reporting) early adopters might be male. http://blog.mozilla.com/metrics/2010/08/26/who-are-our-firef...

Anyway, here's one "female" who uses foursquare: http://twitter.com/#!/Snubs/status/26996595662 :-)

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).

Which is correct? Or am I misinterpreting?

sorry, it is 7% higher than sf's average. this is probably a case of Foursquare's demographic being heavily male [and heavily straight??]

Gotcha. That clears it up; thanks.

Indeed. I noticed that Hooters (between Aquatic Park & Pier 39 in SF) had 27% more women.

The kind that accepts valid currency?

[Edit:

Since the HN crowd seems to like stories, here is one.

One night, back when I was single, a friend of mine and I rolled up to the Blue Room in D.C., decked out in white suits, smelling of day old booze and good times. We had fire in our belly, and barely a sandwich each, with some change burning holes in our pockets, ready to be thrown out like confetti, at any reasonably priced vice. Not to get religious, but we felt like Mickey Rourke and Billy Bob Thornton on a pilgrimage to Vegas, sans the cream '59 Impala, of course.

We walk in, more attitude than stature, two short Arab guys, escorted in by vintage house music, courtesy of the resident DJ, and shamelessly head to the first pair of women closest to the door. Quick awkward introductions, complete misunderstanding, wild gesturing and on to the next. As our luck has it, it was the same again, hand waving and written pleasantries ... damn. Third time is the charm, and what do you know, same thing again.

Fuck me dead! If it wasn't clear then, it is now; we hit The Room on deaf night! Everyone there belonged to an online dating community for deaf and mute people.

We came out and headed to 7/11, we each bought a pen and a notebook .. then back to the club. Ali, my friend, an SOB whom I am eager to meet in hell, said: deaf girls don't mind your thick accent :-]
