This is totally nonpartisan: The executive literary editor at Vanity Fair magazine edited Sarah Palin's resignation speech based on the rules of grammar, usage, style, accepted norms of good writing, etc. - oh, and the editor corrected facts, a few of which were wrong. (Edits are in red; fact-checking notes in green.) If you're unfamiliar with what it's like to be edited by a really serious copyeditor, definitely take a look. Maybe it's just me, but I think it's pretty fascinating.
