You don't have to spend the entire day hunched over your computer consuming this information. Maybe, it is as simple as once in a while glancing down at the device that's invaluable to you or many reasons, catching up, or it lets you know when you should know something. But as these things get better and we get more connected in it, it will get more sophisticated.

When you think of a social network, you have these two-way interactions: "Are you my friend? Yes? No? Yes?" Like LinkedIn, it's business oriented, but it's all about establishing connections. You connect to me through my other connections, and that sort of thing, and you sort of define who your friends are. Twitter doesn't have that.

In any leadership position, you're always going to be disappointing somebody.

The most rewarding thing for me has been this affirmation for me that people are basically good and smart, and if you give them a simple tool that allows them to exhibit that behavior, they'll prove it to you every single day.

With Twitter, it's as easy to unfollow as it is to follow.

People are watching TV, they're watching some clips on their iPhone. I mean, some folks are sitting there on the iPhone, watching the Colbert Report, and meanwhile there's a huge plasma TV right in front of them that they could be watching it on.

I think before Twitter people didn't think that way, not in any sort of meaningful or specific way, so what I'm trying to say, if we're trying a bunch of stuff, a lot of cool and great social stuff, a lot of platform stuff, then some of it will stick, and some of it will be junked over. Some of it will be just like the cell phone, you can't imagine not having it.
