Well.. with my full name, "hometown", birthdate.. etc, etc.. it's highly likely that I can become the victim of identity theft.
outside of that, I don't want people that I deal with on a professional level to find my FB account. It's also easier this way to tell them I simply don't have a FB as opposed to saying I won't add them which some people take offense to and that can be detrimental for networking. It's easier than say.. managing two FB accounts or having to censor what I write on my current one.
