Love the idea, my only concern is how to trust that at some point you're not going to include sponsored products?
And on another comment about adding high margin results as "best" you seem very interested in that concept.
I'm not trying to be hateful, but if you're thinking about how to seed results with high margin products for yourself, instead of the actual best results already in the life cycle of your product, I think it's just a matter of (not much) time before any quality you have will immediately plummet. This makes me very cautious about your product. Very.
