Here is a quote from the article:
"Shepp founded Earthsite.net in 2003 to provide marketing, branding, consulting and incubation for environment-focused Web sites. GreenMaven is an
success story, and after several years in the "green" Web business,
Shepp says he has seen a sudden, marked increase in interest over the
past year. Competition for advertising linked to search keywords such
as "Green MBA" has multiplied by a factor of 10 to 20, Shepp says."
