Great idea: This person is teaching English conversation in Brazil, and he has set up this blog (Natively Speaking Comic Strips) to clarify idiomatic expressions that appear in comic strips. He says: "Every day you will be able to learn a phrasal verb and an idiomatic expression in context through a comic strip on my blog... and if you have a Facebook account you will be able to write a practice sentence in a post on my wall... and then I will correct it in a comment to you."
He also has a facebook fan page for the blog.
