The biggest problem I have with twitter as a platform and as a concept is that individual tweets lack any and all context. "Threading" together tweets doesn't make them linear. If you want to restrict post size, then you have to make threads linear or you wind up losing any and all context farther down the thread. There winds up being a large group of people who try to argue things that have already been said further up the thread or you have people arguing over a misunderstanding because they missed the first 10 tweets because somebody they know retweeted the 11th because it had a snarky soundbite.

Twitter right now is all noise and no signal. It's a bunch of people running through a crowded train station where everybody's shouting but nobody can hear more than a few words of what any single person is saying. How can that ever be a useful platform for civil discussion? It does make for a great broadcast platform. "The train from Chicago is leaving in half an hour. Mick wishes his mother a happy birthday."
