I love markdown, but it's such a mess. There are too many competing specs out there. @ernest, have you worked with the Lemmy folks on this before? This is probably a lot lower priority than stability/performance/efficiency stuff you've got roadmapped, but it might be nice to try to build some consensus on a markdown spec amongst the community.
EDIT: actually, I should check the git repo and see if anyone has filed an issue. You're already way too busy and I've pinged you several times when I should have taken the initiative and filed issues myself. Sorry, Ernest!
