Everyone have their different reasons for making a personal decision and if we actually had the chance to speak with Satoshi, he would definitely have different reasons for staying anonymous and not wanting to join discussions about bitcoin. Question one, my answer will be no and my reasons are, I consider staying anonymous for my safety and besides observing the growth with the anonymous pattern is the best. Participating in development discussions still requires revealing your identity, if he should reveal the secret is a personal choice and I will do so cause during that time the information is irrelevant but it seems his children will inherit the respect, even if Satoshi reveal such secret to his children I'm sure his children will not disclose such information to the media or anyone.
