The last time we’ve seen a new Twitter user with this kind of popularity was Oprah when she first joined Twitter. Mr. Gates proves that he is not not only the world’s richest man, but one of its most popular it. His legacy as an entrepreneur and a philanthropist are far from forgotten.

Putting the numbers together, that’s about 12,500 Twitter followers per hour, or ~208 new tweeps per minute. In reality though, Bill’s follower count escalated after Caroline’s tweet, meaning his real rate of growth is about 20,000 new followers per hour.

Kudos to you Mr. Gates!

For a more professional definition, TwitterFox is a Firefox extension that notifies you of your friends’ tweets on Twitter. This extension adds a tiny icon on the status bar which notifies you when your friends update their tweets. Also it has a small text input field to update your tweets.

I’ve been using it for more than a month now and it’s really one of the easiest way to get updated to your friends tweets. So if you are a twit, might as well try to download Twitterfox!
