I'd want someone to actively promote my product based on a per sale basis and skip out all the idiots trying to just simply bring a lead in. 70%+ of all leads are FAKE and 1% of the 30% left generate sales. You can see a big loss of cash there so you move on to sales. You pay a decent net 7, make sure that your product isn't going to bring people to a charge back, and finally you deliver the goods and both the affiliate and you are happy. As for YouTube I think I would fantasize about affiliates promoting some games or some service of mine in front of real viewers (I am not talking about paying per view basis) so sales are generated.
Then again, I'm not looking for the lint change that most people hunger for (revealed by posts on here), but rather the big fatty pots of solid gold and diamonds people tend to think are to hard or over saturated like actually providing a product or service people want.
