Hey Jeff,
For me, it’s been working wonderfully for the last two years.
I have 15-minute slow mode enabled on the entire site by default, and it’s really improved the quality of the discussion. Sometimes I raise it to 2h, or even 24h, preventively purely due to the nature of the topic and my expectations about it.
If people are able to edit their posts instead of posting more, it makes it more likely that they’ll go back and review and refine what they said instead of word vomit onto the thread.
Thanks a lot for the continued features on Discourse, it’s really a great gift on humanity and I’m not being facetious.
