In the peepcode screen cast Geoffrey Grosenbach said he visited the Tilde offices and got to talk to the creators (Tom and Yehuda) for a day. I think the general audience could benefit from this kind of immersion.
Perhaps you could produce an “Ember JS with director’s commentary” video. Basically have Tom and Yehuda walk through the API docs and source code Class by Class, Method by Method. And briefly, explain the intent behind each thing. Tell a little story about each part of the code when you can. Perhaps up to a minute dedicated to each class or logical segment of code.
Some people learn better when they have a visual or audio association with an abstract concept. Helps the reinforce the memory synapses.
I loved the play by play stuff that peepcode does. Would really love to see more of that from the Ember creators. Bring on more people from the core team to discuss specific aspects of the source code.
Over a few beers it could be a really entertaining walk though of the source code.
Plus I hear Tom needs people on google hangouts.

Could make it a regular thing. Fireside chats with Tom and Yehuda.
But seriously this kind of engagement would be great.
