I’m not precious about material. I kind of like that Twitter might decrease the “lifespan” of a joke, because then you just gotta come up with more and I enjoy that challenge. The danger for a comedian on Twitter is the same danger that any civilian faces: sometimes you gotta put that phone down and go live your life. When you’re on Twitter, you’re not living, and if you’re not living, you’re not taking in stimuli with which you can create new material. So don’t mistake using Twitter for participating in life.
