Eh, twitter seems like a website perfect for celebrities, because it's designed for people who can't shut up even when they're on their own. "AHH! Thoughts are coming! I have to distract my brain!"
And that's why you end up with ridiculous tweets; "In a cafe, having a croissant. Well, waiting for it to cool down! LOL!". No, if I were going to use twitter, I'd use it to be really stupid, hilarious and, most of all, to make fun of the people who do that.
"Waiting outside the classroom waiting for Mr. Erwin to show up. Again! LOL! #stupidity". Of course, it would only work if people knew I was making fun.
