BetaNews | Blogosphere Doubles Every Six Months

"If you think everyone and their mother has a blog these days, you're probably right. Web log aggregator Technorati released details of a study Monday that showed that the site now tracks some 27.2 million Web logs across the Web.
The site indexes 75,000 new Web logs every day, an average of one every second. The percentage of those bloggers still updating their sites three months after its creation remained about the same at a little over 50 percent. It also found that at least 2.7 million of them update their Web logs at least once a week."
