Im joining in on the reddit ditching thing, and was kinda worried at first that i wouldnt be able to like use it the way i did reddit as it feels like a whole new place, but after engaging with posts and people and actually being a part of lemmy rather than being lurk mode all the time i was pleasantly surprised with how easy it is to become a member of the community, theres a reasonable amount of subs (or whatever the other word for em is) that fit my interests, enough linux content and shitposting for my liking, and the overall random posts made by people equally fed up with Leddit. (also i admit i used reddit a little cus there was this post on the fedora sub showing how to fix a sound issue i been having after a recent update)
I'm having fun exploring the fediverse and learning how this all works. There is a decent amount of chatter on lemmy already which adds to the joy of scrolling.
I have found myself getting into an unfortunate loop where if I'm on my lemmy I accidentally end up on another instance and then get all lost at how to follow a community on another instance. Lemmy also seems to load really slowly for me, but that's not the end of the world.
Kbin solves a lot of these issues even if it's generally rougher around the edges. Having a clearer "front page" without getting lost in instances and communities helps a lot. Everything loads faster and I don't end up unable to interact after clicking a link.
That's my pretty initial reactions. I'll go play with it all some more and probably have a better feel later!
Ending up in another instances community then not being able to easily check out that instances other communities has been problematic for me as well - especially on the Jerboa app on Android. Definitely on my wish list for future adjustments and additions.
Also totally with you on the front page issues. Would love to see a way to group subbed communities.
