AMP idea sounds good but it does not convince me that it is mandatory to include amp.js via CDN. Why not via bower or other package manager?
It it also clear that Google Will push it by giving higher search ranking to sites that implement AMP, and also has a partnership with Google.
In fact I am working as a consultant for an italian newspaper and their competitor was contacted by Google to be an early adopter and partner.<p>Aside that it looks ok, and probably I will make my blog AMP compliant.
