I'm making great use of most of Yoast's WordPress SEO plugin, but the one feature I don't know how to use is the 'social' feature, with the Open Graph implementation.
So far as I can see, there's no documentation provided for it.
I've got the "add Open Graph meta data" box ticked, but when I experiment with adding a post from my site to my Facebook status, none of the meta description or title shows, nor is there an image from the post. It's just the URL.
I'm also uncertain of the "Use a Facebook page/ app as an admin" buttons - what are they for?
