Hobbes, your points are all well taken, especially on the actual climb where people tend to resent advice from strangers. I've been offered really bad advice in the wilderness, with strong conviction, so it goes both ways. At least the advice gets peer reviewed here on the Whitney Zone. Your example is perfect actually - the kid you educated really wanted to learn and he appreciated what you taught. Most people don't want advice, some just want to argue about things, but the information is valuable for some out there. And there's another group that will quietly learn but never acknowledge they read it on the internet.
Education is about creating the conditions for learning and providing the information in a non-threatening manner, but in the end, its up to people to teach themselves.
