How much personal info do you actually disclose to Facebook?

[Amelia]

I was wondering, how much do people acutally disclose about themselves on Facebook, so that they can become targeted marketing subjects? Here is what I disclose:

- gender
- age
- location
- work place

Many of my friends / colleagues have the same profile, but gosh, there are so many sublte differences between us (I didn't mention there that I am married, have a child, I am a foreigner, what languages do I speak, I might be interested in philosophy classes on DVD but also on efficient storage solutions for my household). How much info does the average facebook user actually disclose?

Don't be foolish, don't give any personal information.

just my hobbies and stuff, then my gender, birthday, not location, high school, and friends.
