Today I was playing around on Facebook’s advertising interface

Today I was playing around on Facebook’s advertising interface, and found myself learning a little more than I want to know about Facebook’s employees. Facebook is happy to tell prospective advertisers how many of its own workers are into kinky sex stuff. (40, FYI.)
You probably know that Facebook makes its money from letting advertisers precisely target users based on what they put in their Facebook profiles. Using Facebook’s ad interface, you can target, for example, only male graduates of Dartmouth who live in New York and who have expressed interest in kickboxing and Harry Potter. Facebook’s targeted ads make privacy advocates nervous, since they can do things like out individual gay users.
They can also shed light on the sexual practices of a whole company. As you can see, Facebook says about 40 Facebook employees are into the, uh, non-traditional sexual practices I chose to target. Not bad for a company with 3,000 employees. (Of course, many people on Facebook claim to work at the company but don’t, so a lot of these probably aren’t employees. But that doesn’t stop Facebook from claiming to sell access to 40 kinky Facebook employees.) To help advertisers, Facebook offers an estimate of how many users fall under the demographics you’re trying to target. Unlike a normal Facebook search, this estimate includes people who have made their profiles private, since everyone sees ads regardless of their privacy settings.
So, log in to Facebook, click on create an ad, and see what you can find out for yourself by targeting different combinations of organizations and interests. You can learn all sorts of interesting stuff.
