Would be good if your facade could obey law of Demeter. That means that a facade is a unified face to the outside world. So instead of @facade.user.posts you should rather try to implement @facade.user_posts. This is rather a general guideline and is not always the best solution.

For Law of Demeter, the best way should be to use SimpleDelegation or Singletons which don’t mess around too much in the system and remains same throughout.
