The main reason I went into blogging is because it leaves a very small carbon footprint. Unfortunately, many bloggers have decided to make careers on the speaking circuit as “blogging experts” — so many, in fact, that the greenhouse gases they emit during their fetid lectures (including carbon dioxide and, in at least some embarrassing cases, methane) have begun to threaten the blogosphere’s fragile ecosystem.

We know that pengins would catch fire and the planet would die if everyone in China had a car; that much is obvious. By the same token, can the Blue Marble survive the hot air generated simultaneously by thousands of bloggers who market themselves as experts, polluting the ether with BS-generated carbon?

Maybe we need a version of Todd’s Power 150 that awards marketing bloggers a rating representing the number of trees a given blogging expert must plant to compensate for the hot air he or she creates. Ad Age, if you want that idea, it’s all yours.
