Technorati is now tracking over 7.8 million weblogs, and 937 million links. That's just about double the number of weblogs tracked in October 2004. In fact, the blogosphere is doubling in size about once every 5 months. It has already done so at this pace four times, which means that in the last 20 months, the blogosphere has increased in size by over 16 times.
Things don't appear to be letting up either. With the launch of MSN spaces and the continued significant growth of popular blogging and journaling tools like Google's Blogger, SixApart's LiveJournal, AOL Journals, and proliferation of software like WordPress and Movable Type, the number of people out there blogging has jumped in the past few months.
