There is a noisebridge account on twitter. It's usually used for announcements of meetings and such, although assery, full or half, is not out of the question. Feel free to follow us there.
Also, the noisebridge account follows various members who opt-in. This allows for a centralized way of finding all of us who wish to be found, for various twitter-related projects. Here's the opt-in list (If you're a noisebridge person and want to be followed, please put your name and twitter username here).
