"Please take this down and write your own book."
This is a good illustration of how tone doesn't come across well in writing.  Reading the comment by the original author, it sounded like a friendly request to please take the content down.The guy whose site it was clearly didn't see it that way and responded as though he'd been viscously attacked.  He ends up coming across as quite angry, when more likely he was just rattled and feeling defensive.I guess the takeaway is to always take a step back before responding when you feel attacked.  Chances are you're not being attacked nearly as harshly as you think.
