LinkedIn
2
LinkedIn was good for about 5 months in my opinion. It's exciting at first to join groups and see your logo get more and more dotted.
But other than that:
Has it increased my business? No
Have I ever received a single shread of business out of LinkedIn? No
Do I know any of the people I'm connected with on LinkedIn? Yes, my brother and parents
What it is good for: Free Job Posting - you can find cheap workers. If that is what you need, sign up asap.
Future of LinkedIn?
Dead in the water for me.
