It appears to me to be only a virtual fix that gratifies the need for exposure.
If one has a twitter account for the sake of making new friends, well I think it's reasonable to say that it's possible. But as far as marketing tool....it's seems un-likely. Perhaps I'm wrong. In this case, I would love to be wrong...I hate to think that I have wasted my time when I could be more productive in other ways.
Let me know...honestly...if you tweet, just what has it done for you?
