I guess what I'm trying to say is it shouldn't be as much about the platform as it is it the Merchant, the Product, the JV offer and the relationship the Merchant creates and nurtures with their respective JV/affiliate partners.
Some platforms offer benefits that others don't, and I'm not saying the popularity of a platform doesn't matter ... at all, just saying that it should not override the JV relationship, which IMHO is the center of importance and the long term goal.
