Like others here, I dumped Reddit and moved here (and to Mastodon) full time. I also moved to Linux full time on my home laptop and haven’t missed Windows one little bit. I’m looking forward to experimenting more with a couple of other distros of interest (currently Pop_OS) and am having actual fun using my computer again. Heavy emphasis on adopting as many FOSS alternatives as possible in ‘24, and starting to separate myself from the big G.
Maybe not exactly what you’re looking for, but if you know of a program that already does the thing you want, you can search for a variety of alternatives on alternativeto.net. It lists paid and FOSS alternatives.
I saw these a few days ago and they reminded me that I am a moderator of a sleepy little community. 😆
Thankfully the mod tools were very effective in banning the user and nuking comments.
