Technorati founder David Sifry continues his excellent quarterly reports on the "State of the Blogosphere" -- a statistical roundup of the blogs seen through the lens of Technorati's gigantic blog-scraper. Here's the big picture:
* Technorati is now tracking more than 57 Million blogs.
* Spam-, splog- and sping-fighting efforts at Technorati are paying dividends in terms of the reduction of garbage in our indexes, even if it does seem to impact overall growth rates.
* Today, the blogosphere is doubling in size approximately every 230 days.
* About 100,000 new weblogs were created each day, again down slightly quarter-over-quarter but probably due in part to spam fighting efforts.
* About 4% of new splogs get past Technorati's filters, even if it is only for a few hours or days.
* There is a strong correlation between the aging and post frequency of blogs and their authority and Technorati ranking.
* The globalization of the blogosphere continues. Our data appears to show both English and Spanish languages are a more universal blog language than the other two most dominant language, Japanese and Chinese, which seem to be more regionally localized.
* Coincident with a rise in blog posts about escalating Middle East tensions throughout the summer and fall, Farsi has moved into the top 10 languages of the blogosphere, indicating that blogging continues to play a critical role in debates about the important issues of our times.
