title: Should I use Facebook FQL?
body: <p>I am using Koala gem to interact with Facebook Graph API. <a href="https://github.com/arsduo/koala" rel="nofollow">In its Github</a>, the authors mentioned that Koala also supports Facebook REST API, which will be deprecated in the future, and give this example:</p>
  
  <pre><code>@rest = Koala::Facebook::API.new(oauth_access_token)    
  @rest.fql_query(my_fql_query) # convenience method
  @rest.fql_multiquery(fql_query_hash) # convenience method
  @rest.rest_call("stream.publish", arguments_hash) # generic version
  </code></pre>
  
  <p>My take from this is that <code>FQL</code> is a part of the REST api, and that I shouldn't use it if I don't have to. I couldn't confirm this by googling.</p>
  
  <p>Is it true that FQL is part of REST api? If so, should I avoid it when possible?</p>
