Dave has posted Part 1 of another round of his now regular State of the Blogosphere reports. Part 1 is about Blogosphere Growth.

Here is the Summary:

* Technorati now tracks over 27.2 Million blogs
* The blogosphere is doubling in size every 5 and a half months
* It is now over 60 times bigger than it was 3 years ago
* On average, a new weblog is created every second of every day
* 13.7 million bloggers are still posting 3 months after their blogs are created
* Spings (Spam Pings) can sometimes account for as much as 60% of the total daily pings Technorati receives
* Sophisticated spam management tools eliminate the spings and find that about 9% of new blogs are spam or machine generated
* Technorati tracks about 1.2 Million new blog posts each day, about 50,000 per hour
* Over 81 Million posts with tags since January 2005, increasing by 400,000 per day
* Blog Finder has over 850,000 blogs, and over 2,500 popular categories have attracted a critical mass of topical bloggers
See his blog post for pretty charts and lots of details.

With all due respect to Dave

1. 9% of new blogs are spam - that's the tip of the iceberg is what he's going to find

2. Technorati seems to have started searching through and indexing posts on yahoogroups mailing lists after y! wired an rss feed into its service .. and that typically turns up a whole lot of stuff that I for one wouldnt describe as a blog. [not sure if they index googlegroups.com as well] And probably that'd account for the extremely high figures quoted.
