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)
My biggest gripe is that there isn't a working Lemmy iOS app in my region, yet.
I have spotty metered mobile internet connection, and while the web app is lightweight enough, it requires the downloading of page structures each time and it adds up after a while.
I do hope we'll eventually get high-quality apps to interface with the fediverse, much like Apollo with Reddit.
