When Elon Musk has any news to share, you’re likely to hear about it first on Twitter. You’d think the guy who runs SpaceX, Neuralink, Tesla, The Boring Company wouldn’t have much time on his hands.

But as his companies grow, so do his number of tweets. They’ve been increasing steadily – as the Wall Street Journal notes in this graphic. His tweets are so frequent that when he announced he was taking a break from Twitter that one time, it made the news.

Ever since he opened up an account in 2009, he’s tweeted about 16,000 times. Other famous billionaires tweet far less. Bill Gates has sent 3,000 tweets. Jeff Bezos less than 300. This is said to be Mark Zuckerberg’s account which isn’t even verified. He’s sent 19 tweets.
