Musk has been vocal about his goal of turning Twitter into a so-called super-app, something akin to China's WeChat . For now there's no American equivalent to such an app, but industry experts imagine an app that encompasses basically anything a person wants to do online. "Consumers of the app can do a lot of different things on the platform, whether it's listen to a podcast, shop, watch videos," said Nii Ahene, chief strategy officer of marketing firm Tinuiti.

If Twitter's push into paid subscriptions is successful, it could eventually expand into sharing some subscription revenue with users. "In theory, they can become a more mainstream version of Patreon or other similar platforms," Ahene said. "Whether they succeed remains to be seen. It's not the reason people go to Twitter today, so to reposition the company … would take significant investment and time with what's really a skeleton team." What's with the letter X? Musk appears to have a longstanding fixation on the letter X, dubbing his very first startup X.com. (After a merger, the app became PayPal, although Musk reportedly pushed for it to keep the name X, according to biographer Walter Isaacson.) After buying Twitter, Musk reportedly texted Isaacson that he was "very excited about finally implementing X.com as it should have been done, using Twitter as an accelerant!" The letter X surfaces throughout Musk's other endeavors as well, including his space-exploration venture SpaceX, his recently launched artificial-intelligence app xAI and the Model X, one of electric car company Tesla's earliest models. Musk even refers to his son with singer Grimes, by the name X. "It's just X, the letter X," he said on the Joe Rogan Experience recently, explaining how to pronounce his son X Æ A-XII's name .Musk regained ownership of X.com six years ago. He formally changed Twitter's legal name to X Corp in April. Over the weekend, X.com was redirected to Twitter.com, and on Monday a crane began to remove Twitter's iconic bird logo from the company's San Francisco headquarters. However, police stopped the work soon after it began. A worker stacks letters removed from the Twitter sign on Twitter headquarters in San Francisco, on July 24, 2023. Getty Images
