My first impression of Twitter was that it was trivial, annoying and pointless. But I suppose you have to figure out what it might be good for before you can submit it. For me, the idea that you can have SMS style news feeds from Spacecrafts and Telescopes was pretty amazing.
This page gives you a list of some of the twitter feeds associated with Telescopes and SpaceCrafts. I expect to expand this over time.
