As the first LR evangelist (there are many now) at my workplace I am always curious how you guys do what you do. Looks like pure magic.

I've poked around in the console a fair amount but would be really interested in two things you listed above:

- "We use the MutationObserver API for capturing diffs of the DOM"

- "We use Protobufs as a wire format for reducing bandwidth"

I know you all write pretty awesome JS articles on a regular basis but I have so many questions about how LR works! Spill the beans but not the secret sauce!
