State of the Blogosphere 2006
As of January 2006, Technorati estimates that 75,000 new blogs, or approximately one blog every second, come online every day. Of these, half are still kept current three months later.
Technorati currently tracks 1.2 million blog posts per day, or 50,000 posts each hour. The frequency of postings fluctuates, largely based on current events that bloggers write about, though the overall trend is upward. In 2005, posts spiked on the death of Terry Schiavo, the revelation of the identity of "Deep Throat," the retirement of Justice Sandra Day O'Connor, the London bombings, Hurricane Katrina, and the hearings for the confirmation of Samuel Alito to the Supreme Court.
