The blogosphere is doubling in size every six months and is now 60 times larger than it was three years ago, according to the latest quarterly installment of David Sifry's "State of the Blogosphere" report. He writes that Technorati now tracks over 35.3 Million blogs. On average, a new weblog is created every second of every day - more than 75,000 new blogs created every day. Technorati also tracks about 1.2 million new blog posts per day, or about 50,000 per hour.
Some 19.4 million bloggers (55 percent) continue to post three months after their blogs were created (in the previous quarter, 13.7 million blogs were active, 50.5 percent). Moreover, about 3.9 million bloggers update their blogs at least weekly.
Although spam blogs (splogs) and fake pings (spings) have increased overall, "the high level of interesting, original content being created greatly outweighs the fake or duplicate content listed on splogs," writes Sifry.
