title: How do I route user profile URLs to skip the controller?
body: <p>Right now my user profile URLs are like so:</p>
  
  <p><a href="http://example.com/users/joeschmoe" rel="nofollow noreferrer">http://example.com/users/joeschmoe</a></p>
  
  <p>And that points to the <code>show</code> method in the user controller.</p>
  
  <p>What I'd ideally like to do is offer user profile URLs like this:</p>
  
  <p><a href="http://example.com/joeschmoe" rel="nofollow noreferrer">http://example.com/joeschmoe</a></p>
  
  <p>So, what sort of route and controller magic needs to happen to pull that off?</p>
