The most interesting thing is their revenue model:

Unlike other social networks, which waited years to monetize through advertising, Pinterest has taken a different route. They’re monetizing already by taking a cut on sales that pins on their site help generate. They partnered with a firm called SkimLinks, which automatically scans through every link posted on the site to see if it goes to a retail site with an affiliate program. If it finds that kind of link, it secretly adds an affiliate code that ensures Pinterest will make some cash from sales that derive from that link. It’s a clever game, particularly given the site’s users’ retail focus, but Pinterest probably should have disclosed the practice more openly.

Interesting!
