Facebook: Poking People Since February 2004

A study conducted in Washinton DC has "discovered" that Facebook targets ads according to users' stated sexual preferences.
I know - whoda thunk it!

EDIT: The Daily Mail went big on this on Saturday 22nd. 'Facebook 'accidentally outing gay users' to outside firms through targeted ads'.
But like their coverage of Tyler Clementi's suicide (after film of him getting intimate with another man was put on the internet), the angle was more about the Mail's technophobia...
