Proving that you can’t rely on engineers and algorithms alone, Pinterest CEO Ben Silbermann says marketing made the company what it is, today. “The way Pinterest grew had little to do
with Silicon Valley wisdom,” reports AllThingsD, citing a presentation given by Silbermann, this weekend. “It was about marketing -- mostly grassroots marketing -- not better
algorithms.” Among other efforts, Pinterest hosted meet-ups, took fun pictures of attendees, and convinced bloggers to do invitation campaigns.
