It's been one whole year since the world's youngest libertarian started blogging, and one year later he's still going -- and still the world's youngest libertarian! It's frightening to think where young Callum is going to be in a few year's time, but it's sure going to be exciting to watch.
To celebrate his blogday, he's begun to repost his series on skyscrapers. Excellent choice. And well done, young man.
