Yet, often non-technical topics are upvoted massively, indicating big interest in HN community in this topic. So you are saying we should enforce the opposite, because 'this is Hacker news'? Not much of a difference to me as indifferent bystander, 2 extremists discussing whose side is more righteous if you ask me.

A random example - astronomy, my pet love, is discussed here often, yet rarely articles themselves have anything to do with 'hacking' or technology. I don't see much protests against that.
