Vinod Khosla drops $3 million on health startupVinod Khosla's boutique VC firm Khosla Ventures has lead a $3 million investment round in ZocDoc, a startup which aims to make it easier to schedule doctor's appointments online. Managing the bureaucracies of the healthcare industry, with a nest of on- and off-network providers, HMOs and the like would make the ancient Greek civil servants of Byzantium blanch. Health revolutionaries from Steve Case to Google haven't exactly set the healthcare industry on fire, so good luck with that. Considering Khosla is struggling to convince his own son to eat vegetables, it's a good thing he tapped Khosla Ventures partner David Weiden to sit on the company's board.
