"How to Avoid Flamewars" by Dave Winer
Winer would be the last guy I'd picture writing this article considering how many he's started. I think this MeFi comment pretty much sums up why people hate Winer, as do many of the comments here as well as this diagnosis. The guy has started or extended more idiotic flame wars than anybody, so you can see the irony in him writing this.
Before you know it, we'll see "Eloquent Speech" by Mike Tyson, or Courtney Love's "Guide to Responsible Parenting" (thanks Waxy for that one).
