title: URL logic: unique short description and id
body: <p>What is the logic behind a URL like this one: </p>
  
  <p><a href="https://foursquare.com/v/the-deli/4f3258b9e4b09c2f1061fc5b" rel="nofollow">https://foursquare.com/v/the-deli/4f3258b9e4b09c2f1061fc5b</a></p>
  
  <p>v is probably an abbreviation for "venue".<br>
  But is there a specific technical reason to add both short description and id after that?  </p>
