I'll take a wild guess, predicated on the fact that twitter is another social platform that's difficult to monetize: sponsored pinboards.

My company would pay to have "sponsored pinboards" all day long if the net ROI was positive. But that's a huge "if".

I think that pinterest needs to be careful on how many of these "sponsored pinboards" they have. It is currently something cool and hip, but if the ratio of "sponsored pinboards" and user pinboards isn't correct, they can turn off a lot of users.
