A month ago, I posted commentary on the rising influence and rapid growth of weblogs.
That post included comment on how many blogs Technorati tracks and what blog growth looked like. I quoted figures from Technorati as at the end of July when Technorati reported it tracked 3 million blogs. When I posted my commentary on 13 September, the then figure was over 3.8 million blogs – an increase of nearly 30%.
Technorati’s CEO David Sifry has provided some new figures on what’s been happening since then.
Today, Technorati tracks over 4.1 million blogs – up 10% on a month ago. In fact, according to Sifry, growth in blogs tracked by Technorati has been doubling at a regular pace, and the blogosphere (definition) is now more than 8 times as large as it was in June 2003. In addition, the slowest rate at which the blogosphere has doubled in size is once every 5 months.
Sifry says there are about 12,000 new weblogs being created each day, which means that on average, a new blog is created every 7.4 seconds. Not all blogs are regularly posted to, though – about 45% of all older blogs have not had a post in 3 months, according to Sifry. This may be due to abandonment, hosting service switches, tyre kicking, or other factors.
