AV on Dragon's Eye

Just watched Dragon's eye reporting on the Alternative Vote referendum. I'm biased. I really cannot see any case for AV at all. Guto Bebb (as always) made some very good points for the 'No' side. Could not see any sense at all in the 'Yes' case that Peter Hain was making. AV is more confusing to the voter, sometimes declares as the winner a person other than most voters first choice, and is a system that almost no country in the world uses. But why on earth did they have to link the item with the frivolous Eurovision Song Contest. The referendum is a serious issue and should be treated seriously.
