title: Which Ruby gems support the Facebook API?
body: <p>I have a rails application using the Facebook API. I've seen several different Ruby gems for integrating with Facebook, but they look dated. </p>
  
  <p>Is it best to write low-level calls myself? Is there a decent and current gem available?</p>
  
  <p>Have any of these gems changed recently?</p>

  <p>I'm beginning a new project -- which gem should I use as of September, 2012?</p>
