It was an incredibly small minority and the positive feedback far outweighed the negative. I did feel the need to highlight the hate as I think it's pretty indicative of the automatic assumption that we are all selfish, money grabbing salesmen.
Life is like that; minority ruins it all. Better to focus on the great feedback. Still, I'm surprised that HN users acted like that.. maybe there's something we don't know. But anyhow, I feel sorry for you as it was a great initiative. Good luck in your next startup :)
