Recently we published a written introduction to Drupal 8 called, "The surprising thing about Drupal 8 is how unsurprising it is".
Last month, I gave a live version of that introduction at the Atlanta Drupal User's Group. Here's a video version of that presentation.
In this video, I'll give you a tour of the new features and admin interface changes in Drupal 8.
There's not a whole lot here for people heavily involved with Drupal 8, but hopefully this is eye-opening for those of you who aren't yet familiar with Drupal 8.
