exactly, exposing the backend with HTML is harder, if that is supposed to mean the complete interface which includes CSS and javascript. without interface it would just be XML, at which point JSON would be the better choice. even more, many backends can be simple CRUD. i reuse my backend for all websites and haven't had to do any custom backend coding in years. so my current backend cost is zero, because i can do it all in the frontend.
