I was expecting something different. I thought this was going to contain solutions for building web apps at scale, but it's basically a way to build plain old websites with a somewhat nicer and more maintainable syntax.

Some things that I want to see solutions for:

* Implementing richer controls that can behave as if they are native to the platform (e.g. building a better date picker that is fully encapsulated from the perspective of the developer)

* Dealing with styling at scale (tens of thousands of lines, up to a dozen levels of element nesting)

* Encapsulating application modules so they are incapable of conflicting with other application modules (in structure, behavior and styling), and can have a separate lifecycle from the page they are loaded into.

To me those are the real problems in building web apps at scale, and I was expecting to see solutions for these.
