I still get those the wrong way around [text url] often enough. I only mess up MarkDown slightly less often because I write more of it. The "() is more common than [] in regular text, so it makes parsing-sense to start a special markup code with []" is going to help me with that, though. That particular mnemonic only works for coders, though :) Also, doesn't MediaWiki syntax sometimes also have a pipe | between the url and the text in a link? Or is that only for internal links?
