May be satoshi is still around and reading this post. It's the biggest mystery of 21st century.
Maybe it is, but it could also be so that if Satoshi was publicly known, we would not have had the freedom of speech and free trade to the extent that we have it at the moment. Perhaps my words may seem too veiled to you, but honestly speaking, I cannot imagine the massive adoption of Bitcoin if it had a public "shepherd".
And frankly, I disagree with your statement regarding the mystery of the century. The thing is that, one way or another, there are still those who partly have information that could violate Satoshi's confidentiality, and I'm almost sure that this information is only temporarily hidden,
(and the removal of one of the first threads is a confirmation of this).
