On Mastodon, you can pick an instance with a higher limit. The one I’m on has a limit of something like five essays worth of characters. Vast majority of messages are around 100-500 characters, but occasional you see someone actually put that higher limit to good use. I think Twitter/X has a limit that doesn’t really match the current need people have. I do understand the historical background behind it, but I don’t think that’s a good reason to keep dragging this historical baggage around.
