I think Meta already forgot Threads.

I don’t see a use for regular hashtags on Lemmy

Discoverability is still a weak point for Lemmy, so adding more ways to find content would be useful.

Who implied this would be done haphazardly?

Also, there’s plenty of use for tags. They’re already on Kbin and work great.

Kbin already supports this, and it makes it a lot easier for Mastodon users to find and interact with Lemmy content. Hopefully Lemmy gets it soon.

So things should never improve?

a single instance can get knocked out without talking out the whole fediverse

Honestly, it may as well have in this case. LemmyWorld is the de facto “hub” for basically the entire Threadiverse right now. All the major communities are seeing the most activity through LemmyWorld. While I’m subscribed to a lot of communities from other instances, sometimes duplicates of ones found on LemmyWorld, losing LemmyWorld would still a huge chunk of the content that I’m trying to see.

I really do wish that more specialized instances would sprout up and that some of these communities could cluster together across multiple pockets of the Threadiverse. I feel like this makes it less likely to lose huge chunks of content, and also makes fewer large targets for somebody to want to attack in the first place.
