A blog a second

That's blogging's rate of growth, the BBC reports: Somewhere in the world, a new blog is created every second, according to blog tracker and search engine Technorati.com's fairly conservative figures. Last summer, the rate was every 5.8 seconds, as TheRegister.com reported back then. That's 14.2 million blogs right now, up from 7.8 million in March. So the "blogosphere" (or blogging world) has doubled in five months. The Wall Street Journal's "Numbers Guy" looked at blog-measuring last May. For parents new to the concept, the New York Times has "Blogs 101."
