So, there are a number of questions in which the MHO simply isn't relevant. I understand it's not really that big of a deal, but for those who dwell on their MHO percentages, it would be nice if question askers could disable MHO for a question - that way not getting MHO wouldn't count against anyone's MHO percentage, and people who are interested in MHO would have less reason to avoid answering it.
Prime examples of the sort of questions that don't really need an MHO are the "how do I look?" questions, or the "Is it big enough?" questions..
Very good point most of my MHOs are randoms or automatic - I am on 14% but I feel my actual earned ones are somewhere around 5%. Personally I would ban MHO altogether people should just answer questions they want not worry how it affects my MHO percentage.
