Nice of them to link here, it's still a small community but that's not always a bad thing, and neither is moving away from reddit as much as possible since things there are just going to get worse there. It's still early tech but it works well most of the time and has really great potential, especially now that it gained popularity and additional developers/funding due to the reddit boost.
As for @guildwars2, I don't think we're able to connect to them at all for some reason. I can't find them in the browser to subscribe to them, and their kbin page (https://kbin.social/m/[email protected]) is 404-ing meaning it was never even synced (nobody ever subscribed to it).
