I would have to concur with Marshall Kirkpatrick. I also now use Twitter as a working tool, not just for ‘status upates’ (which I don’t really do any more unless I can say something vaguely informative or funny). I use it to interrogate and interact with my work and social contacts. It’s now one big ongoing conversation which can help me in my work, and especially in writing stories. I also was one of those who broke the story about Google buying Jaiku, and I got that because of seeing a Twitter post from a contact. As Marshall says:

People laugh at Twitter, and they can go ahead and laugh for all I care, but I’m here to tell you that it can be invaluable. Aside from the personal connectedness and relationship maintenance it’s good for, let’s be honest – it’s paying my rent. (Thanks Twitter!) I don’t mean they’ve hired me as a consultant, though I would love that, I mean Twitter is great for news discovery.
