title: Constantly updating numbers
body: <p>I want to create a number on the page that says something like <code>1,299,282 images viewed</code>. The number <code>1,299,282</code> will be grabbed from the database table as the largest number in the auto-incrementing column <code>id</code> using <code>select max(id) from listings</code></p>
  
  <p>This number does not need to update AJAX style without reloading the page, but will ideally change on page reload if the max <code>id</code> did indeed get larger.</p>
  
  <p>Is there a way to cache this, as the number only changes every 10 minutes. Or will caching this be too much work?</p>
