I don't mean to be a Debbie downer but even I have trouble enjoying Lemmy because of some of it's problems/quirks. I don't think it'll be anywhere near as popular as alternatives with those problems present. I hate it but that's how I feel. I hope it gets better

Adding to this, Snapper (snapshotting utility for btrfs) has a way to enable snapshots after each install of an app, and I'm pretty sure there's a package somewhere that adds btrfs snapshots to grub entries, so you could theoretically boot back into a stable version of your system pretty easily
There are things like w3m and other text browsers. I could maybe even get away with curl if I knew it better.
I watch a lot of YouTube, so I could maybe utilize the YouTube downloader cli tool so I can watch them locally.
I try to make a habit of using the terminal for as much as I can, which honestly is a lot. I've even found a way to use it at work.
One day, I plan to run Linux without a window manager, maybe even without xorg entirely, using the tty's exclusively.
Pages not loading or error'ing out, general usability stuff, like pictures in the feed snapping back to small/icon size causing the feed to jump around, posts opening in the same window and going back takes me all the way to the top/start of my feed, the confusion around interoperability between instances (can I just log in with my account on another instance? Do i need a new account?), etc.
I'm on mobile, so maybe that's a large part of my complaint, but when ya come from Reddit, it's hard to not see things Reddit does well that you miss.
It's also very likely some of this is simply user error, I am not an expert, but I feel like if it's confusing or not intuitive for me, then it's probably room for improvement.
Edit: Idk what changes were made in the most recent update to Lemmy but a lot of my complaints here no longer appear to me occurring, so that's great news!!
