I saw this HN job post (http://news.ycombinator.com/item?id=2802652) from WebMynd where they make fun of a hypothetical pet coupons site. I am sure working for WebMynd will be technically rewarding than working for a pet coupons site!... But how many of you think a pet coupon site (if executed well) will make more money than WebMynd and therefore monetarily more rewarding for a developer?
