Just wanted to share that I've had great results be including call to actions at various points in my Facebook Fan Page. These are mostly to click the 'like' button if they have not already, and I put arrows pointing towards the button where possible. Mashable have a good example of this too: http://www.facebook.com/mashable?v=app_4949752878&ref=ts I also include call to actions of how I would like them to interact with my fan page, what I would like them to discuss. For example if it is about Laptops I may say 'Tell us what Laptop you Have - Do you like it?' Works well for getting more engagement from your fans.
