I am using this plugin as an alternative to ones that just don’t seem to hold up too well to page optimization.
Your plugin is falling down however when it comes to grabbing the meta content for Facebook. It is not ignoring  text / code and hence grabbing code at the beginning of a post rather than starting with content.
Otherwise your plugin is holding up nicely.
I should add that the bracket  code I am referring to is other short-code in the post at the beginning… if that matters.
