The 50 Who Matter Now

In our second annual ranking, Business 2.0 has compiled an unabashedly subjective list of people, products, trends, and ideas that are transforming the world of business.

Evan Williams
Evan Williams
Founder, Twitter

Rank: 44

Why he matters: When we say You have questionable judgment, Williams's Twitter may be a case in point. Twitter gives each user a webpage, where short text updates (known as "tweets") can be posted to the site via IM, SMS, or blogging tools. The result is a torrent of short notes and inane observations (from "Feeling sick today" to "I'm in the bathroom!") pouring in from buddies throughout the day.

Fans say Twitter is an invaluable way to stay in the loop. We're not so sure. Twitter is either a major new communications platform or the next overhyped Friendster. Which will it be? Ask us again next year.
