Well, after endless haranguing by one of my co-workers, I finally broke down and got on Twitter.
I'm still in the evaluation phase, but I see some utility to it. Just need to balance the usefulness against the potential time-sucking productivity-killing aspect to it.
Anyway, you can find my tweets at http://twitter.com/devhammer. And if you have trouble getting there, you can always check http://istwitterdown.com/ (sorry, that domain just cracks me up).
And if you're local to the DC, MD, or VA area and are involved in the local developer, please drop me a line with your Twitter ID so I can keep up with what you're doing.
