LinkedIn / The Whole 9, etc

Anyone else here a member of one of these? I signed up on them both. The Whole 9 is a bit of a mix it seems - looking for a bit of fun but trying to network.

LinkedIn - just kind of interesting on how the network is built etc.

Are there any other possible business networking that might be worth checking out? (Yeah I do have a MySpace profile but I never go there). It seems like I am signed up everywhere but not too much networking. (Probably because I am too busy signing up!) LOL

AdultWhosWho ?

Samebb, do you know your button is missing in your sig? You sorted that thing we discussed on ICQ?

Thanks for that one... I did sign up - just waiting to be approved (unless some company will adopt me) LOL
