Though how will this handle people pinning other people's products? Does the pinner get a cut if someone buys someone else's product through their pin? How do you verify legitimate retailers?

I guess the question then becomes does Pinterest see it as being worthwhile to buy Etsy out or do they just run them out of the market? Etsy shop owners could simply "pin" links to their stuff and voila off we go. It'll probably come down to the cut Pinterest takes from the sales. If they offer a lower % than Etsy, they'll stand a chance at running Etsy out of the market and seeing a higher conversion rate.
