I used to make a healthy living designing landing pages for affiliates. Several of my clients were making several million a year (all made a "healthy" living) and I was bringing in several hundred a day from just designing landing pages.

Shame many are missing that deep entrepreneurial spirit many here on HN have.

A reason you see many sites with generic Google listings in the first 10 results.
Go to any mainstream web site frequented by an older, less tech-savvy audience like weather.com. Take a look at the text ads on the right side and the landing pages they link to.
There's your crash course in the current state of the affiliate marketing industry.
