I think that is confusing when IRV is "one vote" and Condorcet isn't  
but they use the same ranked ballot.

My taxonomy of Voting Stuff goes:
Result:
	Elect 1. single seat elections (mayor, governor, president)
	Elect Several. multi seat elections (city council, state or national  
legislative body)
	(I don't split out proportional here. I'd call that a result of a  
specific process, split out below.)

Ballot:
	Choose One. choose you favorite. results in plurality
	Choose Some. my city council is elected that if there are 3 seats  
open, I can vote for 3 candidates
	Acceptance. Approval (choose as many as you like)
	Ranked. 1st favorite, 2nd favorite, 3rd, etc.
	Rated. Rate on a scale of 0 to 10, 0 to 100, -1.0 to 1.0, etc.
	Range-Rated. Give a high and low rating if you're unsure exactly what  
you ought to rate a choice.

Ballot-Modifiers:
	Government model based: (why are ballots modified this way? because  
that's how the system works!)
		You can only vote for your party (Primaries)
		Vote for a party
		Vote for a party, then choices within that party
	Election Theoretic based: (this might be a good idea. can be applied  
to multiple ballots and or election methods)
		Automatic Equivalence on Loss Option (AERLO, but now I know I'm  
misremembering this a bit because it doesn't match the acronym)
		Automatic Truncation on Loss Option (ATLO)

Election Methods: (ways to count ballots and reach a decision)
	Plurality/One Vote/FPTP. count up the votes, highest wins
	Acceptance/Approval/Choose N. count up the votes, highest wins
	IRV
	Borda count
	Condorcet {with various tie-breakers}
	IRNR
	etc.


Election Methods can sometimes be applied to other than their 'native'  
Ballot type. Ballot-Modifiers may also modify the Election Method.  
Election Methods tend to be of two sets; different Election Methods  
apply to single seat elections and multi seat elections. Or there will  
at least be modifications to the single seat election method to  
generalize it to multiple seats.


As for Wiki, wouldn't it be awesome if it were a sort of  
proposing/voting system like was mentioned a few weeks ago, with  
instant proxy representation and the works? Yeah, I think I'll write  
one of those. Mmm, web toy.
