I’ve created a new gem called interesting_methods that gemifies what some developers already do (add an interesting_methods method to all their objects). http://smallcity.ca/2018/03/23/interesting-methods-gem.html

I’ve also created a screencast using the gem that illustrates a technique I sometimes use to learn about unfamiliar gems and objects I’m working with: http://smallcity.ca/2018/03/23/method-driven-development
