Blogging Growth
Posted by Sam Churchill on August 4th, 2005
David Sifry, who developed the leading blog tracking software, Technorati, has a three part series; The State of the Blogosphere.
He and the team at Technorati put together some high level information on the growth of the blogosphere, both in the number of bloggers as well as the growth of new blogs per day.
Sifry says, “MSN Spaces, Blogger, LiveJournal, AOL Journals, as well as a number of international hosted services are growing quickly, and use of software like WordPress and Movable Type to provide blogs continue to grow significantly”.
Summary:
- Technorati was tracking over 14.2 Million weblogs, and over 1.3 billion links in July 2005
- The blogosphere continues to double about every 5.5 months
- A new blog is created about every second, there are over 80,000 created daily
- About 55% of all blogs are active, and that has remained a consistent statistic for at least a year
- About 13% of all blogs are updated at least weekly
“As you can see by the black trend line, posting volume has followed a strong upward trend”.
There’s also been a significant jump in tools making it easy to post to weblogs, including Flickr, TextAmerica, Buzznet, del.icio.us, and others, so posting can be as easy as tagging an interesting link or snapping a photo on your cameraphone.
I’d like to point out as well that Technorati’s median time from post to index has now dropped to under 5 minutes. That means that on average, public blog posts are indexed by Technorati in less than 5 minutes after they are created or modified, and are thus available in our search and tag results.
In Part 3: Tags and Tagging, Sifry says;
First a look at the total number of blog posts with tags. The pickup rate has been nothing short of remarkable, over 25 Million blog posts with categories or tags, as shown in the chart below:
I can honestly say that no one at Technorati was expecting an adoption rate of that magnitude.
Oh, and one more thing: Thanks to our the computer visualization whizzes at the School of Art at Carnegie Mellon University, we came up with a video that shows the growth of tags in the blogosphere. You can see the most popular tags tracked each day as time goes from January (when things were still on a workbench) to late June 2005, when Technorati had tracked a total of about 20 Million tagged posts.
This is the video that was shown at the AlwaysOn conference last month, and we’ve had numerous requests to put it up on the internet. Thanks to a very generous donation of storage and bandwith from our friends at Ourmedia.org and The Internet Archive who have put the video up on their servers. You can watch the 320×160 version or the full size video (coming soon!).
Tags are the new black. Everyone seems to be doing it. People are investing in them, companies are promoting them. They even have their own event,Tag Tuesday. So when I finally got around to upgrading Ecto to its latest release, I was pleasantly surprised by how easy it was to insert tags into the posts. Except for one little catch - the tags were linked to the Technorati site.
Technorati is one of those new open media start-ups that is always making news, for its ground breaking work, or for some not so great reasons.
