Evan Williams is one of the co-founders of Twitter, which is currently a company of only 35 people. The name Twitter is based on the sound birds make to communicate, he says, because Twitter is meant to be similarly fast and light.

Evan's part of a team of three founders, and says his co-founder Jack Dorsey originally came up with the idea. "My co-founders Biz [Stone] and Jack are supergeniuses," he says. "I had been working on blogging for a long time and saw what it did for people. It gives them a way to express themselves and democratizes media. … The beauty is it's very fast. A lot of the focus is that you can do it in seconds." In fact, it's so fast that Evan says law enforcement and fire departments use Twitter to disseminate time-sensitive information to communities.
