It feels like any topic on here is skewed by a factor of three towards the west, and a factor of ten towards the US. You could get the impression that 80% of the world population are doing nothing of relevance.

This is a much more general and tragic insight in fact, the vast majority of human experience is not available to you due to, among many other reasons, language barriers. Consider all the songs, novels, films, music, books and stories that you will never even hear about, because they are written or performed in a language other than the ones you know. If you know a second language, consider all the times you have thought "Oh gee, this is so much easier to express than in my mother tongue" about a neat idiom or grammatical construct, and think of the literal hundreds or thousands of languages that you don't even know the names of, and how full they must be of valuable new concepts and delianations and ways of thought and utterance.

However, I do not know any easy way to exclude all translated from english-speaking sites articles and news to read only local ones.
