HN is for much more than just technical stories. Nearly anything that's intellectually interesting is welcome, which includes lots of articles on history, arts, literature, you name it.

Garden-variety politics and ideological battle pieces are not so welcome, but not because they're non-technical. It's because they're not driven primarily by intellectual interest, i.e. curiosity, and lead to flamewars rather than curious conversation.
