I especially liked how he described the Internet as a "self-cleaning oven" where errors can be revised or clarified much more easily than in errors in print. That's his background as a newspaperman talking, and I know how he feels.
My wife, Karen Juell, one of the best copy editors I've known, coined the slogan, "Error free is up to me." What would the world be like if everyone posting on the Web held that as sacred? Errors are unavoidable (I could tell you about a few doozies of my own), but a casual attitude toward them is something no one with any self-respect should take lightly.
