Agreed. Im so thankful for the few remaining good forums like elixirforum.com etc. So sad that discord really hijacked all of the communities (of course i understand people choose it because it is good but still)
I think it's popular because it's easy / free to set up and the friction is very low for new user, not because it's actually any good.
I think it's actually horrendous for things you want to use forums for. I don't remember using IRC in lieu of forums (did we?), why do we use Discord for the same?
Discord is really good at sucking you into conversation and capturing your attention/time. Its way better than IRC ever was. But that doesn't mean its a good format for information, issue threads, work discussion and such.
Those insights are things I've tried to bake into Booklet - for instance, a really generous free plan and no per-user pricing. Existing community platforms (like Circle) are not set up for bottoms-up adoption, so it ends up feeling like gross enterprise software.
