Help Me Answer This — Specific Blogosphere Stats

Hi everyone, I am trying to generate some specific stats about the size of the Blogosphere. I couldn’t find the answer in Dave Sifry’s excellent State of the Blogosphere reports. Do any of you know of any studies or reports that answer the following:

  • Average number of post per blog
  • Average size per blog
    post
  • Average number of comments per post
  • Average size per comment
  • Distribution of numbers of posts per
    blog across all blogs
  • Distribution of size of posts per
    blog across all blogs
