To follow up on that, the new beta react docs are largely written by Dan, and they explain the concepts very well, more formally. IMO they're a must-read, even if they're not quite final (some sections missing because they're doing each part carefully one at a time). They're a great refresher and/or confirmation that you're "doing it right", and there's many lessons to be brought into how you approach writing and reviewing components.
