Thanks for the comment, Ryan. I think you make my point. If I know the project is called 'cancan,' you're right GitHub results are favored. But when I search for 'ruby authorization,' the only CanCan hit is a blog post from someone else giving an overview of the project.
Not intended that way, in fact, that's the purpose of the article - how to build that community. Even if the code is good, it takes time and there are practical steps you can take.
