Dave Sifry has posted his quarterly State of the Blogosphere with these results including the observation that technology product launches attract a significant amount of interest:

• Technorati now tracks over 35.3 Million blogs
• The blogosphere is doubling in size every 6 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
• 19.4 million bloggers (55%) are still posting 3 months after their blogs are created
• Technorati tracks about 1.2 Million new blog posts each day, about 50,000 per hour

Here are previous reports: February 2006, July 2005, March 2005, October 2004.
