Thoughts about Rails Presenters

This is a collection of links, examples and rants about Presenters/Decorators in Rails.

The "Decorator" pattern slowly started gaining popularity in Rails several years ago. It is not part of core Rails, and there's many different interpretations about how it should work in practice.
