The <meta> defined in kuma/templates/base.html are not all useful and should be removed: <meta name="MSSmartTagsPreventParsing" content="true"> It was used by one _beta_ of IE6. It won't come back. <meta name="ROBOTS" content="ALL"> Neither the original RFC, nor the official extensions supported by Google, Yahoo and Bing have an ALL value. We want "index, follow", which is the default. So no need for this line. <meta name="Copyright" content="Copyright (c) 2005-2012 Mozilla."> We have the official copyright in the footer of the page. And we have a <link rel=""> pointing to it. It is useless (and wrong, not all is (c) Mozilla). <meta name="Rating" content="General"> This is not used by anybody, nor specified anywhere. Useless. We need to keep the <meta charset> and the <meta name="og:...">.
