This is a really good article by Sam Zuckerman at SFGate.com (San Francisco Chronicle):

“More quickly than most anyone imagined, blogging is growing up. From the blogosphere’s anarchistic roots, a professional cadre is emerging that is creating an industry whose top-performing businesses now earn serious money. The industry is expanding at warp speed. Blog-based media could just be poised to elbow aside traditional print and broadcast outlets to become one of the dominant sources of news, information and opinion, many observers believe.”

This is a must read for anyone in the media business. Management or foot soldier.
