And this is why websites like HN exist, and why people use them to discover new blogs :) A lot of times I am reading something, and think: "That's a dangerous advice! Don't do this unless you really have to!" If I post this as HN comment, I will get somr responses, maybe confirming my point, or perhaphs saying that I am wrong and that original advice was good after all. And either way, future readers will be able to read whole discussion and make their own judgement. But if the author asks people to email, I will not bother. Unless my arguments are so good as to convince original author, they will just "disappear" - no one else will read them or respond to them.
