I'm surprised how many people think Twitter is stupid or just a social networking site. You're proposing using it for something useful, but people still think it's for telling people you're putting on socks.
I personally don't have an account, but I think it would be really good if Gaia did updates on Twitter. It's API makes it so it would be relatively easy to embed updates in the website, too.
I do use Twitter and I'm currently following @Fin101, @gaia_devs, and now you, @GaiaBiglanky14. I dunno...I was pretty skeptical of the site at first, sure I'd never really pick up on the whole tweeting craze, but I've found it's interesting to see what's going on with people and businesses from day to day. It's a fun way to keep in touch with friends too, although I generally prefer Facebook, LiveJournal and Gaia for that.
