I keep meaning to write a blog post about the results, but ~99.5% of people paid $0. Of the people who paid, probably around 50% paid the $1.99 I had as default, but what's really interesting to me is the way people priced it if they changed the value. I got a number of payments for amounts like $1.25 and $1.50, and I remember looking at those completely baffled -- who cares enough to pay anything for this (you could just download it for free -- I don't mind) but not enough to pay an extra $0.49? Really wish I had an answer there; maybe people just like 'getting a deal'?
