Earlier this week, chief executive and founder of Technorati, David Sifry released his quarterly, State of the Blogosphere report. David revealed that Technorati is currently tracking approximately 50 million blogs which means the blogosphere is still doubling every five to six months. This is pretty amazing growth and one would think it would eventually start to trail off. The report was summarized as follows:
- 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
As a follow-up to the report, David Sifry discussed the numbers on NPR in a conversation with Scott Simon. You can listen to the discussion here.
