State of the blogosphere, cont.

State of the blogosphere, August 2006. As David Sifry’s report of this name was published 3 months ago, it is now obsolete on blog timescales, so he’s updated it (see link). Lots of figures, graphs and comments. Here’s the bottom line:

  • Technorati is now tracking over 50 Million Blogs. (Maxine adds: the vast majority of which are spam)*
  • 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 .
  • *From "Geeking with Greg" (Linden): "Technorati reported 19.6M weblogs in Oct 2005, but the dominant feed reader, Bloglines, reported that only 1.4M of those weblogs have any subscribers on Bloglines and a mere 37k have twenty or more subscribers. This seems to suggest that over 95% of weblogs, possibly over 99%, are not of general interest. The quality of the long tail of weblogs may be much worse than previously described."
