Hi, Referly's designer here. Yeah, those big huge brands really do have affiliate programs set up that we integrate with and it's an interesting design challenge you brought up, some way to indicate that a site's a recognized vendor in our program before you decide whether to share the link.

This is where I think it helps to throw an app out into the wild and see what sticks, because our idea was more that you could use it as a link shortener in general and that some portion of them would earn money. That wouldn't be the primary reason to share (it'd be to track your influence and show clickthrough rates) but it'd be a nice-to-have bonus if it did, right?
