Personally, I enjoy reading about world news, hearing about TV shows I might want to watch that aren't in my language. I enjoy reading cross-language puns and seeing photos of food I don't usually eat. I enjoy seeing people who don't worry about the things I worry about.
If you don't want those things, if you don't want to know what's going on outside, then that's up to you, but I think that's a sad way to live life.
