Here's a short article from Marketing Vox on October 25, 2005.

(Blogs are indeed time consuming - reading and writing them! But they can be fun, useful and so easy!)

"A best-guess extrapolation of blog-related surveys and data suggests that work time spent reading and posting to blogs this year will consume 2.2 percent of U.S. labor force hours, and work time spent on blogs unrelated to work will take up 1.65 percent of those hours, reports AdAge (via MediaBuyerPlanner).

About one in four people in the labor force visits blogs and on average spends 3.5 hours during the work week engaging with them.

"And, because blog readers tend to be the most engaged readers of online content, it seems for now as though they are not siphoning blog time from time spent reading their favorite new sites, but are rather reading blogs in addition to existing online behavior.

While it's difficult to measure how much blog time actually relates to work, AdAge's analysis estimates that just 25 percent of blog visits directly connect to the job."
