commit: fb200d8 - #595 (2014-04-14 00:44:57 -0400)
From John Mueller this morning:
"One thing to keep in mind is that the marked up image is not used in the same way that authorship is shown in search results, but rather it may be used when our algorithms choose to show information about your business / website in the Knowledge Graph area next to the search results."
That's put a downer on things.
Limited implementation for now but still a bit more control over branding for the sites.
