I was coming in to write this. Rule #1 for these kinds of blog posts: include code samples! Sometimes I want to read long, detailed articles. Other times I just want to look at the "pretty pictures", so to speak.
When discussing structural issues, like routing, code samples will be either deceiving or extremely verbose, because the ideas like that involve interaction of multiple components that simply doesn't happen in "hello world" examples.
Yep, the same is true of the benefit static typing gives you for refactoring. Real world examples where the benefit is really significant are too big to put in a blog post. It should not require too much imagination to make the point clear to an experienced developer.
