I've been on it for a few weeks but to be honest i'm finding it difficult to see how it can be leveraged for what I am doing.
I guess it's the balance between how many chatter posts and how many business posts. I could very easily set up a feed from both the forums and the blog directly into twitter but I would think most people would very quickly work out what my motives are and stop following me
I'm starting to wonder if the time i'm spending on Twitter would be better spent developing content for myself which I think would have far more long term value but I could be totally wrong!
