#1 by far. Linkedin is by far a better option in my opinion for networking professionally. Before I left facebook I started unfriending the habitual offenders that kept posting what they had for dinner, then I unfriended the people that continually bragged about their jobs, then it was the people that continually posted pictures of their pets, then the people that were always down in the dumps, then... I said this is useless. I never made one sale or business connection. I do believe you may be better off having a bogus account and then creating a page for your business or movement, but personally, useless for me. There will be studies down the road how these virtual friendships ruined people. The next Ted Kaczynski will confess to only having 50 friends on facebook before he's executed!
