Liquid Democracy

Also called delegative democracy is the ability to delegate our vote to someone else we trust to be more knowledgeable about a given subject.

Eventual consensus

(This is how I call it. There may be a more appropriate name that I am not aware of) Every voter can change his/her vote at anytime and as many times he/she wants. The vote stops only when a set of constraints is reached (eg. a candidate to an election has convinced 2/3 of the voters). This serves the same purpose as a two-round race except with no threshold effect.
