Okay, I finished social networking...I see now (did not realize it before) how with social networking on line the "degrees of separation" are shortened. If you need to find someone that knew someone lets say in a certain industry you could put the work out and probably have a contact by the end of the day. Personally, I do not like the idea of putting myself out there to anyone, I mean how do you know who to accept as friends or not?
I signed up to LinkedIn (this seems more insulated than facebook or myspace) I had a hard time finding 5 people from my years at UMD (I was not very social, I was always at the library :) ). And again, I felt uncomfortable contacting them...maybe I am just shy!
