I don't find that to be the case either. Anecdotal, obviously, but I've worked for companies that range in size and I never add anyone from work on Facebook. Same goes for my wife.

We joined Facebook in the early days when you needed a .edu email address to join, so I've got a lot of college partying photos up there. I've always seen it more of a private space. Not sure if the time you join and your original perception of the service changes your use.

Wise choice, although I'm sure she has other ways of seeing what you get up to.

I am very methodical about when I add coworkers to my (private) Facebook profile: the day after I leave.

I see my coworkers for approximately 1/3 of my entire week. If I have a question for them it can wait until tomorrow/Monday. I have nothing to gain by them having access to photos of me at a bar with friends or pictures of me at a half marathon or something.

I would be very unhappy if a coworker added me on FB immediately after joining, and I'm the kind of person who's okay with having some coworkers as FB friends. I probably don't know them, and now I'm in a position where I need to reject an offer of friendship from them.

Screw that.

Hell no.

Like the other replies, I do not do this. I work in the .edu sector if that makes any difference.
