David Evans, co-author of the book Catalyst Code: The Strategies Behind the World's Most Dynamic Companies has written a fascinating essay on the impact of blogs.
The blogosphere is one of the biggest and most influential global industries created in the last decade. Technorati tracks almost 100 million blogs and estimates that about 20 percent of blogs are active in the sense that they were updated in the last 90 days. Hundreds of millions of people globally either operate blogs or contribute to them over the course of the year. With 1.5 million new postings a day, blogging likely consumes billions of hours of effort globally. According to comScore, blogs accounted for slightly more than a third of the 173 billion US Internet visitors in May 2006. All told blogs have become a significant source of competition for all of the on and offline businesses that make their living attracting eyeballs and selling access to those eyeballs to advertisers. The blogosphere creates vast amounts of news and opinion. It is one the major destinations of the many readers fleeing newspapers.
He goes on to examine the motivation behind all of this blogging.
