This session talks about View Modes.  Not to be confused with the Views module, View Modes are different types of displays for you content.  The most common example is the Default and Teaser view modes that you get out of the box with Drupal nodes.  The great part about view modes is that you can create the display once and reused it all over your site.

I have recently spent a little too much of my free time looking around different home buying websites.  After many hours spent on such sites, I find myself having an ever increasing pain at how poor some of the sites are, so this is me sharing my pain with you!
