"If I couldn't interrupt you, how would I reach you?" That's the question Dave Evans starts with as a social media strategist focused on marketing and the impact of the social Web on businesses.

Dave is the author of "Social Media Marketing: An Hour a Day," a practical, hands-on guide to implementing and measuring social media as part of an integrated marketing program. In 2005, he cofounded HearThis.com, a podcasting service firm focused on social media and marketing. And in 1994, Dave cofounded Digital Voodoo, which provides strategic marketing services for clients wanting to tap the power of the social web. Working with his clients, he develops an effective, measured approach to using social media and achieving organizational and business goals.

Dave holds a B.S. in physics and mathematics from the SUNY/College at Brockport and has served on ad:tech's Advisory Board and WOMMA's Measurement and Metrics Council. He writes ClickZ's Social Media column.
