The herd stampedes from one fad to another (leaving a few laggards from each generation to pine for an earlier fad). Don't be shocked.

And as always happens, a few guys at the front of the herd make a huge score, add to it by selling their "secrets" to the rest of the herd, increasing its size, and a bunch of people at the back of the herd are left holding an empty bag, wondering what went wrong this time.
