It seems that vote wars have been a problem in the past on this site. I noticed the site tour does not cover how we should vote, and am recommending it be updated to include this information to help reduce the occurrence of vote wars, and to have voting better represent the answers here. I propose adding the following (or a variation of it) as @AffableGeek posted in part of an answer to another question:
Ideally, when you are voting, you are saying "This answer is informative and reflective of the tradition for which it claims to speak." Downvotes mean "this misrepresents the tradition" not "I don't like it."
I am not really sure if vote wars are still a bad problem, but believe to some degree it is a problem.
Well I'm glad you're so certain. ;)
