Twitter, on Friday, April 14, 2023, disclosed that posts with 10,000 characters would now be allowed, but only for paid its Blue subscribers.
In addition, the micro-blogging site now supports bold and italics text formatting, allowing content creators to use those elements to break up potentially huge blocks of text. Twitter chief Elon Musk first announced that the website is making long-form tweets even longer in early March, almost a month after the initial 4,000-character expansion.
While a 10,000-character limit sounds excessive for most casual users — that’s around 2,000 words, or a pretty lengthy essay — Twitter likely introduced the capability for people looking to make money off their posts.
