Wikipedia makes the walls of their castle sufficiently high so that only the brightest and the bravest can scale them. This morning after an hour's work I was knocked back by someone calling him ( or her) self Mean Custard. This confirms a growing impression that sites such as Wikipedia, Twitter, Facebook and Amazon are peopled by precocious 12 year olds. And certainly American. When I posted a short review for Tombola! by the political magazine Tribune on Amazon it was changed immediately to the Chicago Tribune. The Stars and Stripes really does fly over all our battlements.
