Feels like all of the needless junk we shaved off from pages with XHTML-HTML5 transition is slowly coming back in shape of dozens of meta tags and resource links.

Microformats are alright for what they provide and we already use them in a couple of places, but that's not my point. I was asked to make the website shareable on social networks and more mobile friendly. The site is already responsive, so some of it is already covered. I read up on OpenGraph meta tags, added them to a test page, and it worked alright, but then I find out Twitter has its own prefix, so that's even more tags. I read up on mobile icons, and there's a dozen of different sizes. I don't think this functionality that's tangential to the site's contents an purpose is worth so many bytes.
