Measuring the Impact of Blogs

Carl Bialik writing in the Wall Street Journal discusses the number of visitors weblogs in the US are getting. He points out that:

The total number of active blogs — those with a post in the past 30 days — was 3.5 million on May 1, according to BlogPulse. That was up just 30% from last September, even as the site found that the total number of blogs increased nearly 200% over that time. That suggests there’s a lot of dead air out there.

He is probably right, and my blog hasn’t been especially active of late.
