The way I interpret the article is that he is riffing on the fact that Hacker News members are generally interested in startups and likely believe in the constant release and iterate cycles that are used to determine a viable concept or product.

He might be pointing out the fact that those kind of people are stuck on the "random music" idea he used initially and not giving him valuable feedback on his evolving idea. But I'm just guessing.
