Presentation: Backdrop: A Drupal Fork

Khalid Baheyeldin of 2bits recently did a presentation on Backdrop, a Drupal upgrade built on Drupal 7, not a complete rewrite like Drupal 8:

Backdrop is a fork of Drupal, based mostly on Drupal 7.x, and mostly compatible with its API. It also has some features from Drupal 8.x. It aims to provide an alternative that reduces the cost of ownership by minimizing the learning curve for developers.

Check out their powerpoint presentation.

Xplain Hosting is contemplating support for Backdrop.
