Looking at this, I'm not quite sure what the thumbs up/down signify. For example, on the cancer Don't list: Offer unsolicited advice. Telling people what to do when they don't ask for help is rarely a good idea, even if your intentions are the best. The above has 2 thumbs up and 4 thumbs down. I can interpret that two ways: - 2 people agree that you shouldn't offer unsolicited advice, but 4 people think this rule is wrong. - 2 people thing you should offer unsolicited advice, 4 people agree that offering unsolicited advice is a bad thing. It gets more confusing with this one: Be patronizing or condescending. 8 thumbs up, 8 thumbs down. Would anyone disagree that you shouldn't be patronizing or condescending when talking to a friend about their cancer? I have no idea what the thumbs up/down means.
