Discord is where the creative energy is right now, for better or for worse.
Extremely poorly.
I am on 2 or 3 instances, and I cordially loathe it.
Compared to mailing lists, it's a grotesquely over-complicated mess.
To make a comparison with text editors:
Discourse for a mailing list user is like telling a skilled expert in Vim or Emacs...
"Now, to join our community, all you have to do is install a Windows 11 VM and use MS Word 365 for all your editing! Some new users prefer the toolbar. It does all the stuff you're used to and like, but it has a cool new UI! It's great! We all love it and we are sure you will too! We looked at your old system and we have made sure we've included all the old functionality! You can move the cursor left, right, up and down, but now, you can also use an animated GIF or PNG as your cursor and have a choice of colours!"
> Try it and you'll get a bunch of people complaining that inline images are bloat and who needed an auth system anyway and why can't I use my IRC client from 1996 and your client wasn't supposed to use my RAM, I'm saving that for guests.
