Well, I suppose it had to happen eventually. Government by uninformed public forum. The coalition would like the views of the ordinary man on the street on how to save money, because apparently the opinions of their qualified economic expert advisers aren't enough.
And how are they going to implement this? Well, Facebook, of course. Because you're opinion matters, but only if you are registered with a social networking site with questionable ethics and unrealistic farming simulations. Rather than designing a website that is actually designed for the purpose. Or, God forbid, actively seeking out members of the public with whom to engage.
