In justifying his proposed takeover of Twitter, Tesla CEO Elon Musk argued that the platform is “important to the function of democracy. It’s important to the function of the United States as a free country and to freedom in the world.” This lofty rhetoric begs a question: Just how big is Twitter? Is it still growing, or is it a platform fading in relevance? Twitter no longer publishes detailed statistics and declines to answer when pressed for even the most basic statistics, like how many tweets per day are sent.
