Pinterest, which people use to save images to digital pinboards, makes money by selling ads. Since many of its “pins” are products, the company offers “Buyable Pins” so users can shop directly inside its app. Instagram, the photo-sharing app owned by Facebook, has recently made a similar push into e-commerce.

I mean, ok, but still, wat? It strikes me as pretty backwards for a payment processor to buy an e-comm site.
