in a strange way, this almost makes the behavior of hopping onto every new framework rational. The older and less relevant the framework, the more the owner's starry-eyed enthusiasm wears off. The hope that bigcorp will pay $X million for the work starts to fade. The tedium of bug fixes and maintenance wears on, the game theory takes it's toll. The only rational choice for library users is to jump ship once the number of commits and hype starts to fall -- that's when the owner is most vulnerable to the vicissitudes of Moloch.
