LinkedIn is definitely a funny beast. My favorite thing about it is that, unlike other social networks in my life, it's only there when I need it and I don't check it compulsively. If I want to check if I know someone at Company X because they might be interested in something to do with my professional life, I can hop on LinkedIn and see if I know anyone there or have a connection. I never go to LinkedIn otherwise, so I have no problem connecting with anyone and everyone. Facebook and Twitter, on the other hand, I check multiple times a day to make sure I'm not missing something "important" in the firehose, which just wastes tons of time.
