Cryronics Lottery.
Would it be easier to sign up for cryonics if there was a lottery system? A winner of the lottery could say "Well, I'm not a die-hard cryo-head, but I thought it was interesting so I bought a ticket (which was only $X) and I happened to win, and it's pretty valuable, so I might as well use it."
It's a sort of "plausible deniability" that might reduce the social barriers to cryo. The lottery structure might also be able to reduce the conscientousness barriers - once you've won, then the lottery administrators (possibly volunteers, possibly funded by a fraction of the lottery) walk you through a "greased path".
On a completely serious, if not totally related, note: it would be a lot easier to convince people to sign up for cryonics if the Cryonics Institute's and/or KrioRus's websites looked more professional.
