When a plane lands in the Hudson and there's a Twitter user on the ferry taking a picture of it, Boom. That's it. The water is still splashing. Here's the photo of the thing.

I don't think of Twitter as a social network. I think of it as a messaging system that has a lot of social components to it.

Twitter provides a great amount of timely information, but we still need those people to fill out the rest of the story and the context.

The thing that excites me, and the thing that excited me about Twitter, is the idea of a flock of birds moving around an object in flight.

I was writing and developing software for alumnae to be able to connect and communicate.

The two things I use the most are the MacBook Air and my iPhone. Those are my two most-used gadgets that are dented, scratched and smashed.

There's no such thing as a superhero, but together we can world in a new direction.
