When it first came out, Pinterest was considered to be a “social scrapbooking” or photo-sharing site.  The CEO of Pinterest, Ben Silbermann has called it a “catalog of ideas.”  The company has, for the most part, shunned the “social network” label.

Regardless of what they would be considered, Pinterest has increasingly become an image search engine.

On February 10th, the company had announced that they had hired Randy Keller, who used to be a senior engineer with Google image search.  Keller was at Google for about a decade and was part of the image Search Quality team.

Pinterest provided a quote from Keller about why he’s joining the company:

Pinterest is the most exciting opportunity in visual discovery today, and I look forward to contributing my expertise in image search quality and ranking to the team responsible for helping millions of people discovery billions of ideas every day. Pinterest’s unprecedented data set presents new opportunities to build the next generation of search that’s personalized to each person on Pinterest.
