Stuart Buck is one of my favorite bloggers, and definitely my favorite kind of blogger. He's not terribly prolific, but each post is intellectually dense, impeccably researched, and devastatingly delivered. He's an attorney, and that he and others like him use their power for good by blogging improves my opinion of all those who practice law.
Here he picks a myth and dismantles it so thoroughly there is not even a mark where it once stood. Read it all and check his blog when you can.
