1. We think this app is awesome for our power users, the curators, but the majority of our users are actually shoppers so we wanted to reserve the right to create a canonical "Referly app" for them down the road. Long term most UGC communities only have 1-2% contributors

2. It is really an issue of focus, to build a marketplace we have to nurture both sides but in the early days it is difficult to do both well. You raise one side up, make it good enough, go work on the other side, then switch. That's the approach we are taking and right now most of what we have launched is really for the power user who is doing the sharing.
