Markdown's embedded html is a strength, especially for something long-form and structured like a wiki. Of course it requires whitelisting, but that's not terribly hard to do (with the understanding that a markdown parser can be much more anal about bad syntax than a browser). The other wiki syntaxes either allow an html subset (MediaWiki[1]) or aren't used as is (plain creole is about as expressive as markdown-without-html). ReST on the other hand is extensible from the start, but the extensions are specific to the build context and the rendering target (mostly html, epub and latex).
