title: How does Craigslist maps work?
body: <p>Craigslist has a new feature...when you search for things, you can view by map. It places markers (representing postings) on a map and if you click them it shows you a customized listing that shows details about the posting that the marker represents.</p>
  
  <p>CL is using <a href="http://en.wikipedia.org/wiki/OpenStreetMap" rel="nofollow">openstreetmap</a>.</p>
  
  <p>A couple questions:</p>
  
  <ol>
  <li>How does CL do this with the custom markers and the popups etc.?</li>
  <li>Does google maps have anything similar?</li>
  </ol>
