Blogosphere doubles in size every 200 days

With the creation of Young Wolf's new blog, Technorati began tracking its 50 millionth blog.

Okay, maybe it wasn't Young Wolf that pushed 'em over that mega-number, but still....

Technorati founder and CEO David Sifry published his quarterly report on the State of the Blogosphere this morning. The number of blogs continues to double about every 200 days.

Here's a summary:
  • Technorati is now tracking over 50 Million Blogs.
  • The Blogosphere is over 100 times bigger than it was just three years ago.
  • Today, the blogosphere is doubling in size every 200 days, or about once every six 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 two blogs created each second of each day.
  • About eight percent of new spam blogs (splogs) 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 are dropped before Technorati has 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.
