title: Modal Dialog vs Lightbox - who wins?
body: <p>In my mind, both modal dialogs and lightboxes serve the same purpose.  It seems that there is a scale of sexy (but javascript-heavy) on one end, and economical (but boring) on the other.</p>
  
  <p>What drives your decisions to use one over the other?  Or, is there a better way to ask the user for complex data without navigating to another page?</p>
