U.S. workers in 2005 will waste the equivalent of 551,000 years reading blogs. About 35 million workers — one in four people in the labor force — visit blogs and on average spend 3.5 hours, or 9%, of the work week engaged with them, according to Advertising Age’s analysis. Time spent in the office on non-work blogs this year will take up the equivalent of 2.3 million jobs. Forget lunch breaks — bloggers essentially take a daily 40-minute blog break. Technorati, a blog search engine, now tracks 19.6 million blogs, a number that has doubled about every five months for the past three years. If that growth were to continue, all 6.7 billion people on the planet will have a blog by April 2009. Imagine the work that won’t get done then.

And a week doesn’t go by that someone asks me to explain “this blogging thing.”
