he swears he's quitting

Man Bartlett, whose every action requires a manifesto, announces he is quitting smoking, or rather Facebook.
The announcement amuses, coming on Hyperallergic, whose editor organized a show called #TheSocialGraph and for whom Man Bartlett is the poster boy for a "social media artist" (doing performances sitting in a gallery tweeting whatever people say to him, that sort of thing).
Two thoughts on this momentous and self-important screed: "I told you so" and "You'll be back."

Corrections: Hyperallergic's editor, not its publisher, organized the #TheSocialGraph exhibition. Also, it was #TheSocialGraph, not The Social Graph. Apologies for the imprecision.
