What kind of subjects do you (a HN user) expect?
RiderOfGiraffes: From http://ycombinator.com/newsguidelines.html  On-Topic: Anything that good hackers would find
            interesting ... anything that gratifies
            one's intellectual curiosity. 

That pretty much covers it.  Stuff that you're complaining about either contains something that some hackers might find intellectually curious, or sinks without trace.Consider some of the other stuff an opportunity to learn both about stuff outside your current direct interests and experience, and about your fellow readers/contributors at HN.  I've encountered stuff I wouldn't normally find, and some of it has been interesting.Take the opportunity.
