Reddit does shitty stuff, but at least I'm able to find stuff on there. Why Discord took off as a medium to replace forums is beyond me. It's not easily searchable, and search engines can't index it. If people aren't fastidious about replying to messages they're responding to, it's just a nonsense stream of consciousness from dozens of people.
That being said, I hate the formatting of most forums. Reddit and Lemmy's comment nesting is excellent. It's very easy to follow conversations.
