Decoupled Drupal and the Front End

I've seen several presentations on the what and why of decoupled Drupal, and this was the best. I recommend everyone watch this video to see when and why you want to decouple, who is using it where, and when you DON'T want to decouple Drupal (i.e. what you will lose).

This is a triple threat of a presentation - it's informative, densely packed, but also fluid and clear. It's a Beyonce.
