Interface nudges and interface limitations. Which is why I brought up the too-short-reply feature.
I am going to try some notes in text in one of the communities I admin. But I’d still like an option to make the user-specific quote flag forum-wide. And I like the idea of a plugin that detects too many quotes or too much quoting from the prior message.
If you don’t like the idea of Discourse without the feature, that’s fine. Nobody’s brought up removing functionality or changing defaults.
