I don't Twitter but it occurs that might be used in the same way. (Can you imagine describing a problem on the Mac in less than 140 characters? I can't.)
That's not how you'd use Twitter. It would be more to announce your presence or to say "I can help!" when someone Tweets that they wish they could figure out what's wrong their (whatever).
Toss in some keywords at twitter.search.com and see if there are any groups that you think FTM could attract.
