Would it be possible to provide an option in the plugin settings, to make the rendering of the Open Graph tags optional?
Like many other people, I use Yoast's WordPress SEO plugin, which can also add the Facebook meta tags to the header, so there is conflict with this plugin. It would be useful to allow the user to choose which plugin's approach to the meta tags he/she wants to use.
Therefore, adding a "Add Facebook meta tags?" checkbox to this plugin's settings would be a very welcome feature.
