• Technorati tracks 80,000 newly created blogs each day (a blog every second)
• Technorati tracks 900,000 blog posts each day (10.4 posts a second)
• 55% of the blogs Technorati tracks has a post in the past three months.
• 18% of the blogs Technorati tracks has a post in the past week.
• The weekend posting average is 5% to 10% less then the daily posting average.
