>>98570176/mlp/ makes its own content now. 15 years of self-referential circlejerk injokes coupled with the intense evolutionary pressure of having next to no (good) official material for around half a decade has distilled horsefucker autism to such a point that the board has become something of a self-contained ecosystem, even within the context of 4chan at large. A good example would be Mare Fair, a pony convention started by /mlp/ 2 years ago, and currently one of the largest of its kind. I still don't know how they pulled it off.
