OpenTable buys food photo-sharing app Foodspotting

Restaurant reservations site OpenTable says it is buying Foodspotting, a mobile app for finding and sharing photos of food, for about $10 million to help it personalize its service.

OpenTable Inc. lets people book reservations online, or through its mobile app, without having to talk to a person. It's used by about 26,000 restaurants around the world. The San Francisco-based company says it will use Foodspotting's formulas for restaurant recommendations to help tailor OpenTable for individual users.

OpenTable says it recently added photos of food from Foodspotting in a partnership with the company.

Foodspotting's founder, Alexa Andrzejewski, will join OpenTable along with most of the startup's 10 employees. OpenTable says it plans to keep the Foodspotting website and app going.
