Since when has Slashdot of all places become accepting of general mediocrity over personal excellence?
" Perhaps the advice-giver wants to sound smart, or simply wants to avoid the possiblity of having to admit they were wrong (if you make your advice hard to follow, that reduces the chance of somebody actually climbing that mountain and then pointing out to you if your suggestion didn't work). So it's not just that the advice-giver is being unhelpful, it's that they're being a dick."
Well, I'm glad the author cares about the overall performance of his advice across 'everyone'. Personally, when receiving advice, I prefer searching out and researching all reasonable options and choosing the best one for me rather than taking generic advice applicable to a wide range of people. And when I give advice I try to do it in such a way that leaves the advice-taker able to evaluate the options and take the best option for them, rather than giving them advice that may help "anyone" a little bit but won't help them in particular a whole lot. If the advice-seeker doesn't have the interest to look at the options and make a choice that's their problem.
