Yesterday, Dave Sifry posted some interesting data on the growth of the Blogsphere. It was outlined in my previous post, so I’m not reposting that info.

Today he posted more information. It indentifed that there are on average, 10.4 posts per second.

Here’s a summary, which I copied from Dave Sifry’s post:

Summary:

• Technorati is tracking about 900,000 blog posts created every day
• That’s about 10.4 blog posts per second, on average
• Median time from posting to inclusion in the Technorati index is under 5 minutes
• Significant increases in posting volume are due to increased mainstream use of easy hosted tools as well as simple posting interfaces like post-from-IM and moblogging tools
• Weekends tend to be slower posting days by about 5-10% of the weekly averages
• During the day, posting tends to peak between the hours of 7AM and noon Pacific time (10AM - 3PM Eastern time)
• Worldwide news events cause ripples through the blogosphere - not only in search volume, but also in posting volume

On March 14 of this year, Dave Sifry from Technorati presented an interesting document at the Web 2.0 conference. The presentation focused on the growth of the blogsphere.

On Sunday, he published an update.

It’s quite interesting. As of the end of July, Technorati is tracking over 14.2 million weblogs, which is double what was being tracked in March. (7 million, 5 months), and about 55% of them are active. That’s impressive. However, when I looked at the numbers again it struck me that active was defined as having had postings within the last 3 months. While I might consider a web site somewhat active if it had updates every 3 months, I not sure I would think the same of a blog which has a new post every 3 months.

I suppose that ‘active’ is in they eye of the beholder.

According to Dave’s post at Technorati, only 13% of blogs are updated at least weekly. That’s really not a lot. I can’t imagine that the 87% of other blogs are terribly worthwhile for their author’s employers, or for the authors themselves.
