tantek aaronpk, re: Google / 4 options, yeah, they've succumbed to weird politics since day 1 of when Rich Snippets shipped in 2009, and they documented *both* microformats, and a new made-up RDFa "data-vocabulary(.)org" markup that ZERO people had been using to date, because they wanted to "provide options" instead of only documenting what worked then (microformats).
