Bill Gates is many things: software giant, philanthropist, and now Twitter user.

Bill Gates is many things: software giant, philanthropist, and now Twitter user.

As of a few hours ago, the Microsoft chairman is one of the millions offering brief takes on their world to anyone who wants to follow them. I doubt that he'll be sharing what he had for breakfast or bemoaning the fact that his cell phone just dropped a call, but Gates is now on Twitter. Gates has already topped 50,000 followers within just a few hours. He's following only 40 people so far.

The first post by the real Bill Gates was a note that he plans to release the second of his annual foundation letters on Monday, charting the progress and challenges in his philanthropic efforts.

"'Hello World," Gates wrote. "Hard at work on my foundation letter--publishing on 1/25."
