I would like to quickly clarify a couple of points about the Emocracy voting method.
Emocracy is not a method with only three choices per candidate: -1, 0 and 1. There is a fourth choice that is very important: "I don't know".
A voter cannot approve of a candidate he doesn't know. If the voter does not know about the candidate's policies, morals etc. he can always vote "I don't know". This choice doesn't give any point to the candidate (or it gives -1 point if the scale goes from -1 to 1).
