Does Web 2.0 commodify the work of artists? Yes, if it makes them create silly projects like this "Are You Social?" shirt. "The owner of the T-shirt is expected to mark the services he uses with a pen and to wear it in public. What happens when users start wearing their network identities openly in public?" Then users start getting drinks thrown in their faces, that's what happens. Take off the shirt* and have a real conversation.
*then put on another shirt please
