If You Can't Find a Pinterest Pin's Source, Zappos Will Suggest One

Zappos’ new service, PinPointing, isn’t officially affiliated with Pinterest in any way, but its whole point is to make it easier to shop the product-focused go-to social network.  As it stands, unless pins came directly from a retailer’s Web site, they’re merely images of items that viewers would have to track down themselves in order to purchase.  They can be linked from anywhere.
