I only add people I've actually met on LinkedIn. I don't use the "FB, but for work" -aspect of it that much. When I was recruiting, I looked up the people applying on LinkedIn to see if we had any common contacts, sometimes I reached out to them if they could say anything about the person applying. Mostly it's just an online CV that everyone can look up. I've actually just exported the LinkedIn job history page as a CV when I've needed it. All the data is already there.
