"David Sifry, CEO of Technorati, has published his latest State of the Blogosphere analysis. The number of blogs in the world, he reports, has now reached 19.6 million. This number has been doubling consistently every five months for the last three years, a rate of increase that shows "no signs of letup." That means that we can now predict, with considerable confidence, that in approximately three and a half years - no later than the end of the decade - every human being on earth, including infants, will be writing a blog."
