"it's a disgrace how many communities have moved from the open internet into Discord"
Why? Its primary use for me is having small, private communities of people who aren't entirely anonymous to eachother and isn't scraped (too much), commodified and filtered through an algorithm like most of the open internet. I would hate it if suddenly it became like reddit or facebook.
The open web really went down a bad path well over a decade ago and I think its time to hard-turn away from it until things get better. The benefits of everyone abandoning the open web are considerable.
Some people are annoyed because discord doesn't have the archival capacity of an old fasioned message board, and if that's your problem with it you're right, but I think the benefits of fluid accessibility and relative privacy outweigh the problems at the moment.
It's almost like there are different-sized Discords out there, and some people (e.g. you) use only the small ones, while other people are different, and some of them use large Discords.
