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)
yea i think one huge advantage is that theres no specific tos for lemmy as a whole and each instance can just do whatever they want which helps loads when it comes to censorship and moderation, and theres no 1 entity that can just skeet yo off the entire platform if u break some rule (great example is how reddit seems to be silencing ppl promoting lemmy and discussions ab it)
