Thought for the day, before I go head-down and nose-to-the-grindstone for the next 9 hours or so:
There's an conversation over on Pnut about character limits, started when I observed that the 500-character limit on Mastodon and the even bigger limit here means that the 256 limit on Pnut feels confining now. The point was made by @bazbt3 that there were challenges in changing that caused by the ADN legacy; I maintain that eventually the limitations of a dead network will need to be overcome.
I suspect, however, that there are those for whom the 256 limit is sacrosanct, and they will oppose any change no matter what, much as there are Twitter partisans who insist the 140-character limit is defining and wonderful and right.
In other words, people are always the problem.
