Is what you're submitting something "good hackers would find interesting"?
I submit links in the hope of sharing some novel/interesting information with others, and to spawn discussions around a subject I find interesting.

Sometimes, for some people, it does. But still, rule #1 is that it should be interesting, then the commerce and connections (from HN and other sources) will follow automatically.
