Craig Newmark twists a “Batman” quote to jokingly refer to himself as “not the nerd you want, but maybe now and then I’m the nerd you need.”
Newmark, the founder of Craigslist, has since retired from the pioneering website that made him ultra-rich by expanding the world of classified ads onto the internet. But the 69-year-old self-proclaimed nerd says he’s now busier than ever as a philanthropist, with what he calls his particular skills — nurturing talent, directing people toward a goal, synthesizing expert knowledge — in high demand.
