Twitter is fun if you follow the right people...I love it! :3 And comparing it to myspace or facebook doesn't do it justice, it's a different thing (although facebook cloned twitter on their last facelift).
Basically, it's a microblog where you write a short message with what's in your mind in the moment. Then, you "follow" other people to receive their updates.
Some people update it at every 5 minutes saying..."good morning, just woke up", "now having breakfast", "going to shower"....those are the annoying people you must not follow. >.>
Buuut there are people that post only really nice links, pics, videos, or funny comments. And of couse, a slice of life here and there is also fun :3
And yeah, lots of celebs on it, for those who like it. I follow some guys from the game industry, they're always funny. xD
Some sites use it as a small version of their RSS feeds, so if you want to receive their latest updates, that's also an option.
And if you use firefox, you don't have to keep on checking the page to read all,there's an awesome ff plugin that keeps the updates at the corner of your page, so you can read whenever you feel like it =]
It's easier to understand trying it than explaining it, actually.
