Only Windows? HN also has Slashdot levels of ignorance concerning the legal system, patents, copyright, and the music industry, and these are only the topics I know something about. I avoid political discussions, but from what I'm told, those are just as misinformed.
Note that I am no expert in those topics either. I just took the time and effort to research those on my own rather than accept the sound bites media puts out.
When it comes to technology, there's probably no better place. (And even that I would caveat with an exception for Microsoft technologies, where you'll find more FUD than knowledge.) But basically for anything else, don't expect much from HN.
