title: Should I use the Social Plugin to log in or the Javascript SDK fb.Login method?
body: <p>It seems there are at least 2 ways to implement Facebook login on a website: via the Social Plugin or the Javascript SDK.</p>
  
  <p>Social Plugin (FBML):</p>
  
  <pre><code>&lt;fb:login-button show-faces="true" width="200" max-rows="1"&gt;&lt;/fb:login-button&gt;
  </code></pre>
  
  <p>Javascript SDK:</p>
  
  <pre><code> FB.login(function(response) { ... }, {scope: ...});
  </code></pre>
  
  <p>Which one should I use?</p>
