I rarely work with independent programs because there is no accountability as far as payment is concerned. There are a host of issues with working with networks as well, but nothing is perfect. Also I don't want to keep track of all these different earning sources-especially since indie programs seem to have ridiculous terms like $100 payout min on low commission items. I like that everything is combined because I do not promote one merchant at a time.
Also it takes time to build an affiliate program. You really need to understand how affiliates work. You can't just slap up some links (network program or indie) and expect people to jump to promote it. Nor can you send me an email telling me about your great program and think I am going to jump at the opportunity. That's not how it works.
Also, there are many times when I sign up for programs and then don't do anything until months or even a year later. If you don't have any time to invest in a program then I am not sure what kind of results you are expecting.
