I have a client who uses wordpress and a facebook like for every article and page. He wants to be able to display the most liked articles in a sidebar widget. I don't know much about facebook or even use it that often, But i would imagine that for this to work it would have to be built into the facebook code. If anyone knows how to get this working or of a tutorial that would help I would appreciate it. He also wants to do this same thing with Twitter but we can focus on one thing at a time.
