Dan Brown, then online editor at the London Free Press in Canada, wrote in April 2008 that nobody had known what a blog was when he graduated from journalism school in 1996, and that the question of whether blogs count as journalism was still undecided. The remark was singled out at the time as the misinformed quote of the day, on the grounds that the bloggers-versus-journalists argument had been settled some years earlier.
The objection is a category error rather than a disagreement. A blog is a publishing platform, in the same sense that television and radio are publishing platforms. What appears on it may or may not be journalism, and the format cannot settle the question either way — confusing form with content is what keeps the bloggers-versus-journalists argument alive long after it stopped being productive.
There was also a straightforward empirical answer available at the time: five of the twenty winners at the previous year’s Online Journalism Awards were blogs.
