I have to say I absolutely despise Discord, any kind of live commenting, etc. it's just so overwhelming and too 'in the moment'. A lot of what makes Forums so great is that we can have new people commenting on something older, or just having a history of something useful for someone else to find. It's nice to be able to prepare a thought rather than just a livestream of emojis or dumb comments about something.
EDIT: I'm sending them an email about it ..
