Weird Premise of NY Times Article on Business Blogs

Mainstream journos love to denounce blogs as unedited diaries with no journalistic standards. So I can't help but wonder about the research Christopher Elliott did for his NY Times article about travelling business bloggers. The article contains the strange statement: "An Internet search for full-time business travelers who write Web logs produces astonishingly low numbers, considering the 8 million Americans whom the Pew Internet and American Life Project say publish a blog."

Huh? What constitutes "an astonishingly" low number? Whom does this astonish? What did he type into the search engine? Which one did he use?

Hey? Don't you have an editor?
