i think the clown aspect is an extension of the whole DJ worship thing. if people weren't staring at the DJ instead of dancing and interacting with one another, none of the pageantry would be noticed, or necessary.
i've noticed ever since i started spinning that a lot of our local shows are packed with all of the other local dj's standing around, watching someone dj. then those same guys repost this article on FB complaining about clowns in the scene, when they actually helped create the situation that allows those clowns to thrive. derp!!
