The Zen of Just Writing CSS
I like the simplicity provided by scoped CSS, and I tend to name classes in a way that essentially accomplishes scoping.  However, there's this nagging feeling at the back of my mind that if every component in your app has its own stylesheet, your style is maybe not consistent?  It just seems like the ideal website with a consistent and good UI design should be able to have a single stylesheet (probably written in Stylus/SASS).  I don't know if this ever happens in practice, but it's just something I think about.Less on-topic, I feel like the title of this article is wrong: you're not "Just Writing CSS" if you're writing scoped CSS, which requires some sort of build system.
