Recently I was sent a link to a Twitter thread.
Apparently this is a phenomena wherein the twatter submits a series of short tweets, each preceded by a sequence number, which when run strung together resembles something that is almost, but not quite, entirely unlike a paragraph, and nearly manages to communicate a complete thought. It is unclear whether users demonstrating this symptom are unaware that there are places on the internet without arbitrary character limits, or if their identity is so heavily invested in a third-party platform that they are simply unable to communicate outside of it. Needless to say, I retreated to saner shores.
