Forgive my generalization, but I see HN as a handful of groups with some overlap. You have hackers/programmers, business marketing, pure entrepreneurs, and investors/angels. There are people who fall into multiple camps, but stories tend to fall into one of these groups. I think the point you're making is that topics along the lines of hackers/programmers seem to have fallen off in favor of some of the other areas. Correct me if I'm wrong.

Personally, I visit the "new" page as often as the frontpage and find many interesting stories there.
