I’m just going to keep reporting on Pinterest’s growth until such time as it stops having crazy stupid ridiculous growth. Sorry. It jumped 52% from January to February, going from 11.7 million unique visitors to 17.8 million. For scale, Google is still at 186.6 million and Facebook is at 158.6 million. Still, Pinterest, for the moment anyway, is The Blob, consuming all in its path. But if The Blob was super into crafts and fashion.
