title: Choose Graph API or old REST API for Facebook application
body: <p>I should have asked this in Facebook developer forum instead, but somehow I can't register to the forum and the Facebook connect feature is not working at the time I'm writing this.</p>
  
  <p>Anyway, I am still confused whether to use Graph API or the old REST API for my Facebook app.
  Generally, this is what I want to achieve in my app:</p>
  
  <ol>
  <li>Get profile picture and name of the user.</li>
  <li>Get profile picture and name of the user's friends who are also using my app.</li>
  <li>Post into the user's stream.</li>
  <li>Allow users to invite their friends to use the application.</li>
  </ol>
  
  <p>Can someone provide me an insight, which one is better for my application?</p>
