A source close to the company tells Valleywag that Fotolog, the social network and photo-sharing site, has been sold to a large Latin American company for an amount over $100 million. Fotolog CEO John Borthwick, who's on his way to Italy for a family vacation, hasn't returned a request for comment. Update: "As if," emails Fotolog cofounder Scott Heiferman. Still, the rumored sale, if true, makes eminent sense for Fotolog — and for Borthwick. Fotolog, though based in New York City, never took off in its home market. But overseas, especially in Latin America, it's huge. The site, which asks users to post a single photo every day, now counts more than 10 million members. While clearly successful, Fotolog is just one of many ventures for Borthwick, a former executive at AOL and Time Warner — and a sale would free him up to pursue those.
