You now have a very practical reason to subscribe to Twitter Blue beyond long video uploads and the coveted blue checkmark. As of today, Blue members in the US can post tweets up to 4,000 characters long. You can't currently schedule these posts or save them as drafts, but this could be helpful if you'd rather not write a lengthy multi-tweet thread just to share your thoughts.
Free Twitter users can still reply to and quote these tweets. And yes, Twitter is aware that scrolling through a sea of these lengthy posts could be frustrating. Any tweet longer than 280 characters now hides any extra content beyond a "show more" prompt. Blue normally costs $8 per month, or $84 per year.
