as i tooted somewhere else:
there's this thing that you generally only see in religious cults. the leader predicts the end of the world; that date comes, and passes, and half the cultists leave. he predicts a new date; the world doesn't end again, and more leave. eventually he has only hard-core faithful left.
this is what mozilla is trying to do.
