I’m in the minority, but I don’t. I, too, see no point in Discord servers for such obscure things.
Likewise, there’s a Discord for every single subreddit. I guarantee you they are not self-fueling, and will die out soon.
Then there’s Itch communities anyway. Maybe they prefer the real-time chat format for communication (just look at how the FnF kids converse here), but it’s nitpicking at that point.
