Graphic artist Jay Shells (his street name) is about to launch a social etiquette campaign with four very official looking signs he will be posting all over the city. Riffing off of the MTA logo, the signs are tagged "Metropolitan Etiquette Authority." Last year, Shells advised subway riders of proper behavior. I can't wait to see the other three signs. Note: You walking smartphone updaters (especially on 23rd street) deserve forearm shivers to your stupid faces.
