Main reason I prefer Discord is that the live chat aspect to it means I can more immediately address people's technical questions as they come up. It also feels less social and active to talk back and forth through delayed responses like a forum setting does, which is also why I don't really do much on the SnapMap subreddit that I also am an admin for. It's just a glorified billboard to direct people to the more active and maintained Discord server at this point. And as far as I know, there's just the one remaining SnapMap-focused discord server that I run, not really scattered across multiple different places.
