Though, I'm afraid this will be hard to quantify for you. You will also need to satisfy the burden of proof that those links/citations are prevalent ideas and constitute a representative sample of more than just a few individuals.
What's more though, such a representative sample only just informs us about the population of HN commentators. I don't think that is a particularly interesting sub-population, very little (if anything) can be extrapolated other than: "there were a lot of comments on HN stating Y." Doesn't really mean much for me - to be blunt, nobody really cares what random groups of HN commentators think. It doesn't represent very much.
On the other hand, perhaps we can look at actual studies that use statistical techniques to in fact make somewhat more interesting inferences, eg:
