title: Div scrolling with the page in a fixed position
body: <p>Even with firebug I can't figure how to achieve this out:</p>
  
  <p>look at the social div on the left side of the page. It follows you smoothly: which css positioning did they use? I just read an absolute position, nothing more.</p>
  
  <ol>
  <li>I tried the same but it wont scroll in my page</li>
  <li>using jquery and animate makes it too pretty</li>
  <li>modyfing the css on each scroll looks pretty weird, it stuck for a millisecond and then move
  How to get their same effect?</li>
  </ol>
