IMO copying communities from Reddit as-is was a mistake long-term, but was maybe necessary short-term so that people wouldn’t be confused. If I had my druthers, I’d make a new system where communities are uniquely identified purely as !UUID@lemmy.instance
(though still with a human-friendly display name). You don’t get to create a community that namesquats something like !gaming@lemmy.world
. All posts would be made with hashtags like Mastodon, and then each community would just configure “Include all posts with this tag in our community”. The big issue then is who moderates tags? I think a system like Bluesky has would work well, as you mention. People can moderate tags and other people can follow their work, or not.
If that was combined with seamless account/community migration, that would solve a lot of moderation issues. If you mod a community and the admins suck, just move it to a new instance. If the mods of a particular community suck, start your own. They won’t be able to monopolize a common name, so it’s much easier to get traction.
On the long-ago internet, there were many, many different software options that supported the same protocols, and they were also a lot more configurable generally speaking
Lemmy is pretty good about that, actually. It’s interoperable with Mastodon via ActivityPub, and there’s other projects like MBin that work nicely with Lemmy.
The way I’m imagining it, it wouldn’t be microblogging, but I’m probably not describing it well. You’d still have communities with threads, unlike Mastodon. You’d just wouldn’t have people posting “to” those communities (unless maybe you intentionally wanted to).
It’s mostly a way to get at the same thing as merged comment threads, just in a way that feels like it would have fewer edge cases to me.
