I use facebook as a marketing tool also, I'm a member to close to 100 different groups if not more and have gained 2 new team members. Before I started my business with Avon I had close to 3,000 friends because I was very active with facebook games lol. When I went back to school I eliminated them all, keeping only close friends and family. facebook can be a useful tool, with any outlet we choose consistency is the golden rule. In my book at least, you never know, you could be at the right place at the right time.
