title: How powerful is Drupal really?
body: <p>I've been using Drupal for a long time, and know that it's robust and has tons of features. My question is, is it a framework that you can build REALLY big sites on? And can anyone give some examples of REALLY big sites that have been built with Drupal? </p>
  
  <p>To answer my question about whether or not it's a good idea to build really big sites on Drupal, imagine having to redo facebook as a drupal site. Would it be possible (realistically)?</p>
