title: What are some differences between distributed and de-centralized services?
body: <p>I am unable to come up with fundamental differences between the two.  I could only come up with examples:</p>
  
  <ul>
  <li>BitTorrent is a distributed p2p system, but ToR is decentralized.</li>
  <li>Web services are decentralized, but I cannot think of a distributed web-service. (Maybe Diaspora?)</li>
  </ul>
