I am pleased to announce the launch of a new project Argotopolis: the Map of London Slang. This is the product of a collaboration with the artist Adam Dant, images of whose remarkable cartography, and much more, can be found here: http://bit.ly/1L8qJDM. Our map, which features a wide range of the slang that has been generated by London and its many social ‘tribes’, can be found here: http://bit.ly/1edEymQ or here: http://bit.ly/1Gw5Jne
