How big is it?

Dave Sifry updates his invaluable State of the Blogosphere. 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
