Ideas: * content length so that it fits in one screen with the default font (e.g. screenshot essay as a native constraint) * 4000 characters, but as an “attachment” (requiring a click) rather than intrinsic post content
* 4000 characters but only in replies * 4000 characters but you can’t retweet/recast it past 280 (so funneling longer content towards replies, incentivizing a shorter top level post)
