I haven't really looked at Facebook in a long time but also haven't deleted my account because I do use Facebook marketplace sometimes.
I just logged in and looked. I actually saw no AI generated content except the few examples that were posted by people I know. I'm sure other's experiences are different, but the algorithm isn't feeding me slop for some reason.
Norwegians have much easier access to ski resorts than most Americans. In fact, many Americans who want to compete move to places like Colorado and California to have reasonable access. From a quick search, Oslo has similar access to ski resorts as Denver. If I had to guess, though, they're less expensive and more easily accessed by public transit.
Winter sports are also just more popular in Norway. I think this is for pretty obvious climatologial and historic reasons.
