Newmark is a senior Web-oriented software engineer, with around twenty-five years of experience (including 18 years at IBM), and has become a leader in online community by virtue of running www.craigslist.org for over 9 years. He's compiled extensive experience evangelizing, leading and building, including work at Bank of America and Charles Schwab.
In 1995, he started craigslist which serves as a non-commercial community bulletin board with classifieds and discussion forums. Using a common sense, down-to-earth approach, craigslist strives to make the 'net more personal and authentic, while advocating social responsibility through the promotion of small, non-profit organizations.
Newmark's community activities include being on the advisory boards of Climate Theatre and Haight-Ashbury Food Program as well as supporting local writers through Grotto Nights. Newmark has been featured in the Associated Press, the Wall Street Journal, the New York Times, Los Angeles Times, USA Today, Business Week, Time Magazine, and Esquire Magazine.
