State of the Blogosphere : Hockey stick growth

David Sifry, CEO of Technorati, released his State of the Blogosphere this morning.

The highlights:

• Technorati is now tracking more than 57 Million blogs.
• The blogosphere is doubling in size approximately every 230 days.
• About 100,000 new weblogs were created each day, again down slightly quarter-over-quarter but probably due in part to spam fighting efforts.
• There is a strong correlation between the aging and post frequency of blogs and their authority and Technorati ranking.
• Spam-, splog- and sping-fighting efforts at Technorati are paying dividends in terms of the reduction of garbage in our indexes, even if it does seem to impact overall growth rates.

The below graph sure makes it look like I made the right move in November 2003 staking my family’s future on the growth of blogs.
