It really blows my mind how good of a deal reddit has (had?) with regards to content and how determined they seem to be to blow it up.
By that I mean: they make the site, all the content is created for them for free, all the moderation, sifting through horrible porn, nazi shit etc. is done for them, also for free, people create apps to more effectively drive traffic to their site, also for free, literally all they really have to do is run ads to rake in the cash, keep the servers up and try to provide better tools for the free moderators to sort through the free content more effectively.
They only do one of those things reliably, and people still contribute endlessly for free. So really all they have to do is not directly torpedo all the free labour they rely on, and they even fucked that up.
And don’t skip over reading things! I also run Arch with KDE and honestly with almost all problems I have, if I carefully read through either the Arch Wiki (this will probably be your most valuable tool) or the error message that comes up, the answer is usually in there somewhere, it just needs digging up.
Also: if something with a GUI crashes and doesn’t give an error message, try running it in the terminal. So like, if Firefox crashes and doesn’t give any info, try opening up a terminal and running
firefox
from there and the terminal will tell you everything that’s going on. (It’ll be a different command if you’re using a flatpak but that’s the general idea.)
