David Sifry has posted another State of the Blogosphere article on his blog. There is some interesting stuff in there, for sure, but there are some misleading statements as well. Firstly, the count of the size of the blogosphere makes no sense. When one looks at population statistics, one doesn't count all the dead people. Why do the same for blogs? The size of the blogosphere should include a clear description of active blogs. This issue leads to the second - claims about the growth of the blogosphere. The rate of growth has to be moderated to remove the dead material otherwise it is just an accumulation of corpses. Finally, Sifry never makes the distinction between the size of the Technorati index and the actual size of the blogosphere. It would certainly be interesting to do some research to estimate the size of the blogosphere, but looking at the size of Technorati's index would only be part of that process.
Perhaps more disturbing that the lack of clarity in the post is the manner in which the information is lapped up and repeated, by both the blogosphere and other channels.
