New blog every 2.2 secondsDavid Sifry, founder of Technorati, has been watching the growth of the blogosphere. In this update he looks at the growth and rate of growth in the number of blogs.
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.
The blogosphere is doubling in size about once every 5 months.
In the last 20 months, the blogosphere has increased in size by over 16 times.
We are currently seeing about 30,000 - 40,000 new weblogs being created each day, depending on the day. This is well over double the rate of change in October, when there were about 15,000 new weblogs created each day.
Part of the growth of new weblogs created each day is due to an increase in spam blogs - fake blogs that are created by robots in order to foster link farms.
