Last week I got my first friend request from a student. I declined the request and let him know that as a general rule, I won't accept friend requests from students. Now, I don't feel that I have anything to hide on my Facebook account in particular, but I do feel that there needs to be a line drawn between my personal life and my professional life. And while I'm only a TA, I still think it would be inappropriate to be Facebook friends with my students.
I get the sense that a lot of people wouldn't see this as an issue. What do you think? I feel like who you are friends with on Facebook affects what you post. For example, I can't be as open as I'd like because I'm friends with my mom on Facebook. Ok, so that last example isn't a good one because I don't have anything to hide from my mom (hi mom!), but you get the idea. I don't think I would want to be Facebook friends with my boss or my thesis advisor. At some point you need some privacy.
Do you limit who you are "friends" with on social networking sites? Where do you draw the line?
