I actually run my own instance in order to keep a random lemmy from disappearing out from underneath me, although the way that infosec.pub is run makes me more confident about its staying power (I'm on infosec.exchange which is their Mastodon instance, too) Since you asked, these are the major players I'm subscribed to: !android@lemdro.id !aws@feddit.nl !aws@lemmy.ml !aws@lemmy.nerdcore.social !aws@lemmy.run !cloudsecurity@infosec.pub !cybersecurity@infosec.pub !foss@beehaw.org !infosec@infosec.pub !lemmyconnect@lemmy.ca !programming@beehaw.org !programming@programming.dev !rustlang@lemmyrs.org !science@beehaw.org !securitynews@infosec.pub !selfhosted@lemmy.world !syncforlemmy@lemmy.world !sysadmin@lemmy.world !technology@beehaw.org !technology@lemmy.ml !technology@lemmy.world One will notice the regrettable duplication in that list, and it's (AFAIK) a massive unsolved problem in the Fediverse. My mental model is that Lemmy is exactly like signing up to mailing lists but where one can also upvote and downvote posts (err, some instances don't allow downvotes, so there's that). That means that folks who want the most coverage for their submission will post it to every one of the duplicated mailing lists, which results in their own message-id along with their own threaded replies and upvote/downvote scores. Some folks have proposed using the link-url and subject for deduplicating them, but I believe it's just a proposal from the client side and the servers will do no such thing (although running your own instance hypothetically would allow for such customization) There's also https://kbin.pub https://kbin.pub which is its own ActivityPub implementation and behaves a little different from Lemmy, I'm sure with good and bad parts. IIRC there's some federation drama between Kbin and some Lemmy instances, and (AFAIK) Kbin does not have any mobile apps whereas there are currently several which speak the Lemmy API. I'd credit it with "first mover effect" more than one being objectively better than the other I do hope Lemmy catches on and siphons users off of Reddit because the rug-pull from Reddit was a trust-breaking middle finger, IMHO. I wished the same thing for Mastodon, too, but I think the inertia is just too strong with X
