Seattle-based Zoodango, a social site that combines map-based navigation and ratings of local businesses, relaunched nationwide today as GeoPage, according to a company announcement. The retooled site features new data on businesses around the U.S., resulting from a partnership with Citysearch. GeoPage uses an algorithm based on Citysearch and Yelp reviews, Zagat ratings, user reviews, and other ratings from similar sites to rank businesses in a given area.
