I'm surprised more people don't find this interesting because that's a pretty significant conversion rate.
With the volume of traffic Pinterest has, the mere act of appending their own affiliate IDs on URLs before performing a redirect to the online retailer would probably generate so much revenue they'd be in the black in no time at all.
As a way to monetize the site, they should at least take a percentage of the affiliate IDs or add one if it doesn't already exist. It's really silly to leave that money laying on the table for everyone else without taking a slice of that pie.
