I really dislike Reddit's automatic post translation. The translations are poor, and it's polluted my search results with useless information - when I'm searching for something in Dutch, it's because I want information that's relevant to the Netherlands, don't spam me with auto-translated US-centric crap!
And it's always, *always* US-centric stuff. I don't know if Reddit is only translating originally-English posts or what, but it's never anything other than that.
