Anyway, the reason MPFC failed most likely has to do with a sort of Gresham's law of argument quality. If I had to say a point where it started happening, The Mask's run in the Movie Contest would qualify, although I don't know enough about that contest nor about the general rate of argument degeneration to say for sure.
A "good" MPFC will never happen again with the current group of users.
