I find that it's a real test (and enhancment) of my understanding to explain it to others. OTOH, you may just grok it at such a depth that you don't need to go through that pain <s>.

I guess people write books for different reasons <s>. AAR I want to explain whatever you want to know. There are a couple of topics that I see mis-understood over and over, and I've had *some* thoughts about "I could write a book, there's a niche/need..." but I have little inclination to write anything that isn't targetted.
