It would be awesome if you could change the profile-uri from <head profile="http://gmpg.org/xfn/11"> to <head profile="http://purl.org/uF/2008/03/ http://purl.org/uF/hAtom/0.1/ http://purl.org/uF/hAudio/0.9/ http://www.purl.org/stuff/rev#"> for a better microformats handling.
With these links you will cover the following microformats:
- hCard

- rel-tag
- rel-license
- rel-nofollow
- VoteLinks
- XFN
