One of the great joys of Christmas, apart from hyperglycaemia, is the chance to catch up on all the subscriptions and unlistened to podcasts that the tyranny of normal daily-life makes it im-bloody-possible to keep up with. As I blocked out the bickering from the front-seat on the way to my sister's on Christmas Eve I caught up with an episode of This American Life from August (yep, August): 'Superheroes'. One of the episodes posits the great question which superpower you would choose between invisibility and flight; another the blog created to house all the failed superheroes, monsters and villains who never quite made it to a third issue: http://gone-and-forgotten.blogspot.com/
Joy.
