David Sifry's State of the Blogosphere

David Sifry, of Technorati, posted a recent State of the Blogosphere on his blog Sifry's Alerts. 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

If you are interested in understanding blogging in general, the report is only a couple pages, and very worth reading.

One of the things I learned from the report is that I need to understand tags better.
