One of my favourite bloggers, Andy Revkin at the New York Times, draws our attention to the fact that the new White House administration has begun the new reign with an Obama-blog. Or, as Revkin asks, “although for the moment I don’t see a comment string there. Is a one-way blog a blog?”

Obama, well known for using social media to fundraise and organise along his campaign, including Twitter, has famously lost his Blackberry on becoming President. Maybe a comments-thread on a blog is too much to ask? What do you think?
