Looks pretty good to me - thanks, Domenic.
There are two moments, though, that should be clarified, in my opinion:
1. Correct and recommended way of casting promise arguments (with code sample)
2. Cases when promises should NOT be used (for example, using promises instead of events or for passing large amounts of data).

But first, I'd love to solicit feedback from spec authors and readers on what's currently there, and what you think should be there. Is it clear? Is it useful? For those writing specs using promises, have they found its guidance helpful, or have they found other tips that would be good to include? Several of the "guidance" points were drawn from finding mistakes in existing drafts that use promises; are there more drafts we should review?
