I have to agree with you. While I find tech news interesting, I am also a big fan of science news. I'm not a hacker, but I hang around HN because the community seems to filter out very well all of the garbage found on Digg.
I came to the HN because of YCombinator and my ambitions, but I am no longer studying computer science (I have changed my major to mathematics and physics, pursuing what I dropped my first go-around at an undergraduate degree). I stay because this group shares many of the same interests in news. If science posts were to show up, then all the better. If not, then it may be that this group is more inclined towards tech news.
