I’m in Australia at the moment, giving a series of talks in Brisbane, Melbourne and Bendigo. The events have been terrific, with outstanding audiences and discussions. My Observer column this week (published on Sunday, and on Pandaemonium next week) will reflect some of the discussion.

So, this week these is no usual Friday/Saturday post. Instead, a couple of photos taken on a flight between Brisbane and Melbourne at sunset. Back to normal (I hope) next week.
