Facebook groups, discord rooms, reddit subs and the likes just aren't the same, they all feel so impersonal and detached, in some people compete for internet points, in others everything is ephemeral and closed off ... Maybe it's just nostalgia / me being old.
I think it depends on which ones you're using. There are some facebook groups and subreddits I use that still feel very much like a small-forum, where people are generally good and helpful and many of the users are regulars. I haven't seen any discord rooms like that except for some ones that are direct spinoffs of the facebook groups and subreddits I mentioned, so that seems more like a credit to the users than the medium.
I think they have to be pretty niche, though. But to be fair, forums of the old internet also had similar issues where once they reached a certain size the experience was different/worse than when they were smaller.
"As an idea or subject gains wider popularity and interest, the level of passion and laser focus on the _outcomes_ of the idea or subject gets diluted to the average level of understanding of the interested audience for the core subject"
(my weak attempt at describing this issue)
