Earlier quoted context omitted.
It's much older than Reddit but used to be as popular early/mid 2000s. There are topics and the front page automatically tailors to you location (or at least I think that's why I keep seeing UK news). The community has a number of in-jokes that have been running decades, it also has FP comment spam, usually a racist or similar ASCII art comment. That was my takeaway from it...
Ah, that makes sense, thanks for letting me know. But in saying that, I'm in the Netherlands and 100% of the stories on my frontpage were about things happening in the US.
Having said that a lot of the stuff isn't US centric, like recent stories being "Linux Foundation Announces Collaboration for 'Open Radio Access Network' Prototypes" or "Debian 12 'Bookworm' Released" or "OpenAI, DeepMind Will Open Up Models To UK Government"
