о фундаментах

Отсюда:

They say a house is only as good as its foundation, and we believe the same holds true for web applications like Google Docs. With our old foundation, we could continue delivering most features you wanted quickly, but over time it became clear that some just weren’t possible. So we decided to rebuild the underlying infrastructure of Docs to give us greater flexibility, improved performance and a better platform for developing new features quickly.

Aга, я даже знаю что это за новый фундамент такой. Покойтесь в мире, Closure Tools.
