HN is my favourite site by far (I lost my login details to my old acc but have been here for quite a few years), but, HN users tend to be very vocal on areas they don't really "know". My wife is an MRI researcher and I share most threads on that topic, normally saying some comment seems really cool, where she quickly shoots it down as flawed. If it isn't directly related to programming I have a large salt shaker nearby :)

To be fair I know I do the same no matter how much I try not to!
