Sergey Brin buys $8 million duplex in Greenwich VillageA 23-foot balcony, 3,457 square feet of space, four bedrooms, and a limestone bath with heated floors are what Google cofounder Sergey Brin and his wife, 23andMe's Anne Wojcicki, are getting at 744 Greenwich Street for $8.5 million, reports New York's Cityfile blog. The place formerly belonged to Bill Brady, who heads Credit Suisse's Global Technology group in Palo Alto. It'll make a perfect site for more of 23andMe's genetic-testing spit parties.
