I've always been annoyed by markdown for one reason: [Link text](link.url) is backwards.

URLs, particularly Wikipedia links, are so much more likely to have parens in them than they are to have square brackets. And users can choose link text much more easily than they can choose a URL. (Link text)[link.url] would have been much much better.
