It is possible, that Satoshi is/are reading all these bitcointalk contributions ... and although some pepole want him/her/them to come back, nothing happened.
Tell one good reason why Satoshi should come back. (good reason = improvement of Bitcoin)
What Improvement needed for Bitcoin ? maybe best if you also mention something that will tell satoshi of why he must come back and not just random thoughts .
For me it is not the improvement that he must come back but to claim what he deserves to get from His futuristic creation that we all wanted to Thank him personally .
I will not mention tha risk of Him getting out of his Hiding place because of His life and because of the threat might happen from the international agencies .
