Well, it is that time again! It has been almost 6 months since the last State of the Blogosphere, and so the team at Technorati and I have put together some high level information on what we've been tracking. Today I'll focus on the macro growth of the blogosphere, both in the number of bloggers out there, as well as in the growth of new blogs per day. You can compare the chart below to the charts from October 2004 and March 2005.

As of the end of July 2005, Technorati was tracking over 14.2 Million weblogs, and over 1.3 billion links. Interestingly, this is just about double the number of blogs that we were tracking 5 months ago. In March 2005 we were tracking 7.8 million blogs, which means the blogosphere has just about doubled again in the past 5 months, and that the blogosphere continues to double about every 5.5 months.

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. There's a growing number of WordPress-based hosted services that are arising, including Laughing Squid, Dreamhost, and Blue Host, marking an interesting trend - that of ISPs and hosting providers using the GPL'ed software as a differentiating feature of their services. Moblogging sites like Textamerica and Buzznet have also been growing as well, as more people are blogging from their camera-enabled mobile phones. Growth has not only occurred in the US, but there has been a lot of blog growth in Japan, Korea, China, France, and Brazil, to name a few countries.

Here's a view of the number of new blogs created each day that Technorati is tracking, even after removing spam blogs (more on that later in the week) from our index:

You can see the charts from March 2005 and November 2004 to get an idea of how this is increasing, although all the data is included on the chart above. Technorati is now tracking about 80,000 new weblogs being created every day, which means a new weblog is created about every second. About 55% of all blogs are considered active - that is, 55% of all weblogs have had a posting in the last 3 months. In addition, 13% of all weblogs (currently 1.8 Million blogs) update at least weekly.

Interestingly, the activity statistics have remained remarkably consistent over time - In November 2004, we reported that 55% of all blogs were active, which is just about the same number as are active today. I think that this shows that even as the blogosphere is growing at a geometric pace, the "stickiness" of the tools and the willingness to write hasn't changed much at all.

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

Tomorrow I'll give an update on posting volume, which is a better statistic to track the growth of blogging. Lots of people who start new blogs are kicking tires and thus the numbers displayed above could be indicative of a fad in progress - but watching the posting volume shows how many people are actually blogging on a day-by-day basis. I think that is a much better indicator that people are making blogging a habit and a part of their daily lives. Later in the week I'll also describe the rise of tags, the increase in spam (or fake) blogs and SEO, and give an update on the relative influence of blogs compared to the mainstream media.
