I do lean moee towards us defaultism being the case as other country news does get posted but has zero to none interaction because the us posts threads are getting so much more activity.
That's neat. Good on you! I like the platform but to be flushed with ads and pay more ceo salary versus creators like yourself, I rather choose to support those I enjoy my entertainment from. Of course realistically A VERY difficult thing to do. I like the idea of Jaybird and Floatplane to an extend. It's just that if I was more settled with life, i probably could afford it finely but its not that high on my worthy things list.
Stability is really good. No real big issues overtime, running BTRFS and Timeshift. There are some minor problems here and there but more to do with KDE or Arch being Arch I suppose, nothing that stopped me from having a non-functional system.
Not sure what you expect in terms of "support for gaming", It's Arch-based so mostly you're on your own to do that, not from the distro focus itself but everything has worked so far for me.
I don't often use the AUR, most packages come from flatpak if I can or the extra repo from Arch/Endeavour which is trustee packages by default. I added the CHAOTIC AUR to get binaries instead to get faster updates but didn't replace all my packages with them from there.
Netherlands here and as well we have so many local shops that outbeat Amazon that it isn't even fair. There is a very small chance I buy something of Amazon, think the only time I did was for a replacement item for a Dyson.
Wish we had Apple News :(
I generally avoid news of late of any kind as its just so bloated and every once a week or so just visit one of my local sites for a quick scroll.
