Just a thought/question: I have 63 contacts in "Linked In", almost all of them people with whom I share a fundamental client base. Good people; SMART people. Nothing ever happens except people invite me.
On Facebook, I have 271 friends. I sneeze and I get 15 responses.
What's wrong with this picture? Maybe it's that I am not "working" Linked In the way I "work" FB but I'll tell you what...show me who your FRIENDS are...
And I'll tell you ALLLLLLL about you...(-;
