Here are some of the latest stats on the blogosphere from Dave Sifry
* Technorati was tracking over 14.2 Million weblogs, and over 1.3 billion links in July 2005 * The blogosphere continues to double about every 5.5 months * A new blog is created about every second, there are over 80,000 created daily * About 55% of all blogs are active, and that has remained a consistent statistic for at least a year * About 13% of all blogs are updated at least weekly
Technorati is tracking about 900,000 blog posts created every day
That's about 10.4 blog posts per second, on average
Median time from posting to inclusion in the Technorati index is under 5 minutes
Significant increases in posting volume are due to increased mainstream use of easy hosted tools as well as simple posting interfaces like post-from-IM and moblogging tools
Weekends tend to be slower posting days by about 5-10% of the weekly averages
During the day, posting tends to peak between the hours of 7AM and noon Pacific time (10AM - 3PM Eastern time)
Worldwide news events cause ripples through the blogosphere - not only in search volume, but also in posting volume
We now have instant news. Items can be posted in a blog and accessed by the public 5 minutes later.
If any one in marketing or PR is not yet convinced they have to pay constant attention to blogs, and what your audience is writing, reading and being infuenced by, take another look at these stats.
