Thanks for dropping by and taking the time to comment. Reading Mark's book will definitely help you to see the possibilities, and help you to feel not so overwhelmed. Please let me know if I can help in any way. I approach FB much differently than Twitter. On FB I try to connect with folks I already know in real life. On Twitter, I pretend I am at a huge cocktail party, where there are a number of folks I would love to get to know. Those are the folks I start to follow, and when the time is right, I send them a note or retweet something they put out. Eventually some will take notice and you can have a conversation. It's best not to try to play games, but to be genuine in your interest, and your desire to be helpful to others.
Do let me know how it goes, and if you start a twitter account I would be happy to be a follower.
