The Wall Street Journal aims to please and has started the new WSJ Social app on Facebook (in beta). The Journal says they are trying to go where readers spend the most time and are bringing their content to Facebook in app form. After giving permission to the app you can read, like and comment on WSJ articles all while staying on Facebook. It appears also that you can read articles that are not roadblocked by their subscription requirements which so far seems to be a nice benefit.
