It's alright. It's a link aggregator and threaded discussion server like reddit, but federates overActivityPub. It works fine, it's a good way to move community hosting back to the people that use the web. It isn't perfect but it will do.
I personally prefer Brutalinks https://git.sr.ht/~mariusor/brutalinks because it's single community oriented, but development just didn't happen fast enough compared to lemmy to be ready when reddit put the lid on their coffin. I happen to be partly responsible for this, I was the main promoter Lemmy when development started, and while I'm glad to see it finally having it's day, I think some of the early design decisions were bad and I'm sad that to have this explosion of independent communities happen such that we are stuck with them.
