I want to creat a presentation, so I am interested in this question: What are the major advantages of Backdrop CMS over Drupal 8 for a website builder who never uses the API, never programs?
- Backdrop has got Philosophy
- Drupal upgrade is forced by Symphony upgrade
- Planed and scheduled releases
- Lower system requirements
- Layout system
I'd like to expand on this a little. The real focus is on the experience, and not just for the content editor, but for website builders and developers too. The button you think you should should push is the button you should actually push. Text has been updated everywhere to be more human and less robotic. Edit links mean content int stored in the database, and Configure means it's data in .json files. Everything should be where you expect to find it in Backdrop, and it should feel nicer to use.
Also, the biggest difference I see for a non-coder is that Backdrop has less complexity.
