When I select MHO I have certain rules that I follow. I never select anonymous users because it's not helpful not knowing who they are. I rarely will follow anonymity advice either because I find they're a coward.
After that I usually look for one of my friends. If any friends have a half decent opinion I'll do them a kindness and select them.
Then I will look for opinions that I agree with. If there are none that I agree with MHO goes to the person who went to the most effort.

Making me lol, being a gag friend, being really Hot, and being sarcastic all go into the composite index score from which I base my decision for selecting MHO.0
