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 amazed it runs so well. It's incredibly speedy for a wss implementation.
I had a bit of trouble signing up, but was approved super quickly and could log in.
(I might bother support later about it, when things settle down)
Even federated topics are blazing fast. Now I am thinking of setting up my own server on my Oracle Cloud Free Tier.
Markdown works just like old.reddit. But it feels like it already has RES and ton's of plugins preinstalled. I am really quite happy.
Lemmy also understands the language name and wraps the output HTML in <code language=rust>, but it doesn't seem to actually perform syntax highlighting. Maybe that's planned for the future.
