Honestly - I used to think the same way. I've tried Linux multiple times and it never "stuck".
When I got my Steam Deck, though, I realized that the desktop mode was actually quite good. I had tried KDE before and it was always meh at best - slow and usually janky. When I heard that the Deck used KDE Plasma I was worried.
But I had such a great time with my Deck that I realized, "Hey, Linux actually seems usable now." I tried Linux Mint on a Live USB and noticed it got like 90% of the way there, but it had issues with multiple monitors.
Then I tried KDE Neon. And it was great! Multiple monitors worked fine, I have all the tools I need for work, and honestly it's such a step up from Windows glitching out or nagging me with a notification to get Xbox Game Pass or whatever or putting ads in the Start menu.
I've had KDE Neon as my daily driver for about a month now, without a single problem. I recommend giving it another look if you're like me and haven't tried Linux in a while.
And you can follow Lemmy communities from Mastodon.
In fact - I'm replying from Mastodon right now!
The UX isn't as nice as Lemmy natively is, but I can see comments/posts and reply just like they were Mastodon Toots. If you reply to me, it shows up in Mastodon natively as well.
If you click the little "Fediverse" icon in Lemmy, you'll even get taken to my home Mastodon instance. It's a very cool feature.
