Here’s a good thread that’s been brewing over at SitePoint Forums.

“I’m curious to know what type of problems do you experience with even your favorite affiliate program.
- What can affiliate programs do to change how you feel about them or rate them?
- Anything they can do to make it better?
- What is the first thing you look at before signing up to an affiliate program?
- If a program offered perks/incentives for getting X amount of sales, would that increase your chances of joining and promoting?
- If yes, would you promote that Affiliate program harder than the others to reach the incentive goals?”
