I feel the same about Facebook.
Still, when a quake hits (I'm in California), Twitter beats heck out of the news media. And Iran news was also very valuable.
It's just that this guy was saying that such-and-such an event was happening, and he sounded interested. He said he didn't have Twitter like I'd say I don't have an iPad. But he could get Twitter in less than a minute, check out the event, and delete his account later. I couldn't do that with an iPad -- I'd have to buy one first. So it was good to get an explanation of your point of view.
