Muhlbaum made the leap from print to electronic journalism in 1995 after a stint at Dow Jones Newswires taught him about working in real time. He moved to America Online, where he became the editor of its business news content. He has also worked for MarketWatch. He joined Kiplinger in 2001, handling a variety of content, including business forecasting and taxes. He also writes about cars and car maintenance, for which his degree in American literature from Middlebury College qualifies him not one bit.
