Just a heads up, I'm using the official "Share This" plugin in WordPress to automatically add sharing icons (And FB Like button), and your Plugin doesn't play friendly with it. The ShareThis Buttons vanish from posts. But The FB:OG tags are there, yay! And this works great. I just don't have the FB Like button to use them with anylonger.
There should be "FB Like, Google+, Tweet, Digg, and Share" buttons just under the dashed line underneath: "Samurai of Gaming". But I'm not seeing anything.
