I guess it depends on what you are talking about paying for. $100 for the front page seems cheap, $100 for my one up vote seems to high. So far as I can tell,

I guess it depends on what you are talking about paying for. $100 for the front page seems cheap, $100 for my one up vote seems to high. So far as I can tell, me voting a story up or down in no way effects my reputation( I can't tell who voted an article up or down and I don't get points for it.) It is my comments that carry both my recorded reputation and my actual what my peers think about me reputation. However moving what appears on HN to a money basis would effect how I view the site or more likely stop viewing the site. The signal to noise ratio would change for the worse.
