it's not that you can't have a single, good point fit into a small number of characters, but that good discussion requires more than one good point, and plenty of nuance and thought. it's strictly true that the number limit is arbitrary (and only loosely correlated to 'goodness'), but assuming there is a limit at all, my (simple) point was it should be a minimum rather than a maximum, for better discussion.
