Not disingenuous but I object to PR and will most certainly draw attention to implementations of PR I consider failures.  Enough folks post here who think going to PR will create world peace and cure the common cold and they seem to do this without considering the failures.  Germany and the Scandinavian countries are good examples where PR works as well as it can work.  But since many people want PR since that would  "make every vote count" how do you propose to implement a threshold which does throw away votes?  

As an aside (I know its not your point) making every vote count is a chimera anyway.  Run an election with PR.  Have 6 parties all with some number of seats.  They now go away and scheme and negotiate with each other until a coalition government forms with at least 50% plus 1 vote.  So, do the votes of the other 49% count anymore?  NO, they are not in the coalition.  Votes for the losers are always wasted.  Welcome to voting and democracy folks.
