The Blogosphere 100 x bigger than 3 years ago

David Sifry (founder and CEO of Technorati) has posted is latest State of the Blogosphere report.  As a blogger, I feel compelled to pass this info on to the elearning community.  As the ONLY blogger blogging the eLearnDevCon I feel even more compelled to share.  Let's start with the stats summary:

• Technorati is now tracking over 50 Million Blogs.
• The Blogosphere is over 100 times bigger than it was just 3 years ago.
• Today, the blogosphere is doubling in size every 200 days, or about once every 6 and a half months.
• From January 2004 until July 2006, the number of blogs that Technorati tracks has continued to double every 5-7 months.
• About 175,000 new weblogs were created each day, which means that on average, there are more than 2 blogs created each second of each day.
• About 8% of new blogs get past Technorati's filters, even if it is only for a few hours or days.
• About 70% of the pings Technorati receives are from known spam sources, but we drop them before we have to send out a spider to go and index the splog.
• Total posting volume of the blogosphere continues to rise, showing about 1.6 Million postings per day, or about 18.6 posts per second.
• This is about double the volume of about a year ago.
• The most prevalent times for English-language posting is between the hours of 10AM and 2PM Pacific time, with an additional spike at around 5PM Pacific time

I was going to start into why these numbers are important to the elearning community but I promised to start blogging about the 2 HOWs (How to use the new technologie, and How it effects our jobs).  First of all these numbers should help as part of the data for pushing our cause.  This data combined with evidence-based learning defining how blogs can be used for learning should also help the cause. 
Hey, Kevin!  Any studies for blogs and learning in the works?
