" As I'm already using a framework (there are dozens of them out there), what is the selling point of WCs exactly?"
To provide interop between frameworks, so that we don't need to write the same components 10 times for each framework. We can just implmenet it once, and use a native API to use it from any framework.
"Oh, right. "Use Polymer", how can I ever forget."
There are and will be other frameworks which support the Web Components API.
