The monoculture is dead.
The math is simple: more people are consuming more of everything than ever before, but there are very few hits of real scale. That means that many of us spend our time in niches, not in the center.
Filter culture makes it seem like the monoculture is back because of the velocity and frequency we delivered the contents of our bubbles.
Memes as currency pull the same trick of the light.
Culture is no longer a monolith but a series of microliths with devoted and vocal followings.
