Discord is black hole for conversations with more than 5 people in general. This is true not just for software discussion, but also music, sports and pretty much everything else. In a single-purpose channel, conversations die off as the subject of discussion is constantly changing. If I wasn't online at the time, I can't bring up the same topic the next morning, because it's been discussed already.
Compare this to something like the forums on rateyourmusic.com. There are long-standing conversations about specific topics that are years old. Everything is easily searchable, and can be refined to searching inside topics. On profile pages for artists and albums, you can see links to discussions related to that artist or album. This is elegant design that's extremely user friendly. The polar opposite of that is a Discord server with with 5-6 extremely broad channels, and a never-ended series of ellipses notifying you that someone is about to post another message that will soon be lost to the void.
