The Informer was disappointed to learn this week that Facebook is not going to install a panic button on its network. Gripped as he often is by a nameless dread, it would have made his status updates so much easier. In fact, learning that there was to be no panic button, actually made the Informer panic. Right now he has everything more or less under control, though, which is handy because it’s not easy writing weekly wireless round ups when you’re quivering.
