Craig Newmark is the founder of craigslist.org, a site where people can help each other with everyday needs including housing and jobs. The site has a culture of trust, based on shared values like "treat people like you want to be treated." He currently works as a customer service rep, in no managerial role. Previous experience includes thirty years working with computers for IBM, GM, Charles Schwab & Co, and Bank of America.
He's also working with a wide range of groups using the Net to help each other out, like Donorschoose.org, the Iraq & Afghanistan Veterans of America, Kiva.org (microfinance) and Consumer Reports. He's working on the advisory board of Wikipedia, considering customer service and trust
Craig is also actively engaged with government workers on multiple levels to use the Net for superior public service, and with Sunlight Foundation for government accountability and transparency.
He's not as funny as he thinks he is, but sometimes can't help himself. Craig no longer wears a plastic protector and thick black glasses that are taped together, but is still a nerd.
