I've just taken the AV quiz on the Guardian website and apparently the conclusion drawn from my answers is:
You scored 52 out of a possible 85: A tactical voter or frustrated voter perhaps? You appear to want a different electoral system, and maybe the alternative vote is the one for you.
Obviously they don't have a method for computing a more accurate analysis of my motives:
You scored 52 out of a possible 85: A socialist who thinks that elections are as much about raising political consciousness as they are about the actual result - regardless of which, the prospects of meaningful change are limited so long as the system remains a capitalist one. You want a different political system but regard dicking around with how we vote as nothing more than re-positioning deck chairs on the Titanic.
