I had this idea of a real social event, say on campuses, etc. that would be called "Quit Facebook Party". It would be a themed party where people delete their accounts permanently, the process being projected on the wall for others to see. With the social validation people would find it easier to get over their addiction and stop wasting time on FB. Once it became "cool" to not be on FB, it could spread just as fast as being on it did earlier.
