Walking in the city: reading the tags on the walls: tags: writing and the breaking up of private identities. To become a pack. Tags: not given, not proper names but pseudonyms. Presences that dissolve the media signs of the segregationist city. Tags by Smak47: following Baudrillard, we say: they run across Madrid, they cross Madrid, they run from one wall to the next, they inhabit doors, electricity boxes, windows: tags overflow them, ride them, turning them into bodies activated through writing (“Kool Killer or the Insurrection of the Sign”: 1980: 82). From that perspective tags do not belong to the realm of private property but of territory: tags territorialize capitalist urban space: streets and walls become alive and go back to being collective territories (78). Tags: appropriations of the streets, resistances to representation: likely responses to the enclosures dictated by the logics of capital.
