Good post. Well written. There was only one claim, which was unsubstantiated and I would like to here more about:

What did you mean by "Out-of-the-box it is not ready for production"?

Is this a statement about require.js without using r.js? If it is a statement about only require.js without r.js, would you consider r.js optimized builds to be production ready?

Besides require.js, what other solutions exist for easily lazy loading third-party apis such as Google Maps?

Great post, not only did it present a good argument, but it also explained a bit about AMD which I had never heard of before.

Thanks
