I initially liked how Open Graph 1.2 would properly add all the OG tags, and it validated wonderfully with Facebook. However, the description is wrong.
No matter what post I share, Open Graph 1.2 pulls my site's description, and not my post's description.
I'd prefer that the plugin pull the description from the meta tag, rather than the Excerpt. This gives the ability to support any SEO plugin that overwrites the description.
