The Soul of Wit

I've recently been getting into that Twitter thing. Late to the party, I know. But while I've had what I consider to be a good couple of tweets, I'm still finding it hard to get my thoughts down to 140 character at a time including hashtags. It's an art form. So I keep thinking, why don't I start blogging again? I have a lot of thoughts about #myMSPmove. But why is it that when I sit down in front of the laptop, the words don't seem to be there?
