Shel Israel, one of the authors of Naked Conversations, has written a post about Government Blogging in which he mentions he was in Canada and had Canada's Governor General Michaelle Jean blogging!
I had a quick look at the GG website, and indeed found a new site called Citizen Voices: Breaking Down Solitudes on the gg.ca domain. There is blogging, forums, news, and even chat with the GG herself! I hope to spend a little more time later checking the site, and perhaps even submitting an encouraging word or two.
Oct. 13/06 update: I have now posted a longer write-up over on Slaw.ca here.
