The brilliant web comic xkcd is usually right, but he’s never been righter than in this destruction of alt-med nonsense.
Of course, some will argue that these things do make lots of money, but then those people probably didn’t read the text that pops up when you hover your mouse over the comic…
… or they aren’t used to making reality-based arguments anyway. I’m no fortune teller, but I predict this comic will get sent far and wide for years to come. Especially when someone gets that email from their Great Aunt about that one person who predicted that one thing happening because of that other thing they did.
