A new Technorati State of the Blogosphere report (part one) reports continued explosive growth in said sphere.

An excerpt from the BBC story:

In its latest State of the Blogosphere report, it said the number of blogs it was tracking now stood at more than 14.2m blogs, up from 7.8m in March.

It suggests, on average, the number of blogs is doubling every five months. ...

Technorati is like a search engine that keeps track of what is happening in the blogosphere, the name given to the universe of weblogs.

It relies on people tagging - giving keywords to - their blogs or blog posts so that its search engine can find them.

Free blogging services such as those provided by MSN Spaces, Blogger, LiveJournal, AOL Journals, WordPress and Movable Type were also growing quickly, said the report.

Thirteen percent of all blogs that Technorati tracks are updated weekly or more, said the report, and 55% of all new bloggers are still posting three months after they started.

It also pointed to the growth in moblogs, blogs to which people with camera phones automatically send pictures and text.

Now, keep in mind they consider "active" to be one posting every three months.

I've written before that within five years, every journalist will have a blog, but I have more trouble getting excited about statistics that show just over half of all blogs contribute at least one item to the collective knowledge every three months.

Methinks mainstream journalism is still safe.

Update:

So then I see part two, which deals with posting volume.

While it ebbs and flows with events, the trend line for posting volume is going up, up, up.

Here's the summary:

  • 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
