Internet entrepreneur Craig Newmark created Craigslist, which reinvented the want ads. As he explains, "In 1995 I started helping my friends out by putting stuff together online about events in San Francisco. That project became Craigslist -- but who knew? Now we're one of the 10 most-visited English-language web platforms on the planet."

Newmark's latest project is Craigconnects, an online hub dedicated to charities and nonprofits. The site launched in 2011 as a place where people doing philanthropic work can find people who want to help.

"I'd like to build a way for people doing good work to connect, to learn from each other, protect each other," he says, "and then I want to get out of their way."

Newmark shares his personal Top 10 list for 2012 with SecondAct:
