This is all sad. I'm one of those people who come back here once in a blue moon to randomly talk to people but yeah I think discord is really one of those big reasons people scattered. No the channel specifically but the fact that you can join numerous communities of your liking. People are not inclined to stick to one community anymore. It's like when people went outside and made strong boobs with people outside and now with internet I see less and less people doing the same thing.
I would really like to see the site flourish again. When I joined it by invitation of @Kiboune I really thought it's something special even though I wasn't engaging much with other people. I just have no idea what steps do we need to do to revive it and if we actually need to do so.
We could actually try to revive discord and just make an announcement that everything moved here because this is what everyone use now. It would remove need to pay for servers as much as it's needed, will remove need to worry about payments altogether.
