Voting in a guild is worthless. When people vote for in real elections, they have some pretty dumb reasons why they vote for someone. "I think he's nice." "I like his speeches." "He looks nice." Seriously? Your going to give someone legislative power over you for those reasons?
In a guild, it's even worse. People vote to let people in the guild because they don't mind the person chattering away endlessly and annoyingly in vent. They vote to get a DKP system in place that will make sure they can always get the loot they want. They will vote for policies that they think their friends want to follow. They will even vote in a certain way because they think they are voting the way the guild leader would like them to.
The best thing about voting is it assures the voters will get what they deserve. Not what they want.
