Right, and I am thankful for that. However, my point is that in the entire history of my HN career (which spans many, many hours), maybe 100 people have clicked on that link. Maybe 2 of those 100 people turned around and bought the game (probably quite a generous estimate).

If you do the math, that is approaching $0/hour. It is simply not a good way to acquire customers, nor should it be expected to be.
