One thing I liked about the early days at #twitter was the 140 char limit that made it into a conversation. 280 chars was OK, but as the limits get higher on #Mastodon and other places it's turning into a blogging site. The interactivity of a single thought was low friction, and its more work to decide what to say, and more work to skip over other conversations the longer it gets. (This would have been four tweets).
