Growing up, being a twit meant you were stupid. Twits don't even use number signs, it has to be 'hash tag' which makes it sound like you have to start your comments with a Chic-fil-a french fry symbol.<br />
Like most tools, it could be useful and sometimes is but most people are using it for superfluous crap.
I've recently found that Twitter is very useful in professional realms as a networking tool.
i have yet to figure that stupid site out...
it's a good social network, if you're trying to promote stuff and you have tons of followers. Any other reason is kinda' stupid.
twitter is so popular because every freaking celebrity is on it, its bascially the same thing as facebook but with every single freaking famous person in it. People like twitter because its a way to "connect" or so they say
I see a purpose for Facebook, although there has been many deviations from what it was initially intended. Still, I don't see any point to Twitter, so I refrain from using it.
