I dont know the real reason why did satoshi hide his identity also i never seen satoshi in real life since before. But is it that important to know who satoshi really is? I mean is that really big deal for us to meet and even talk Satoshi in real life? Because for me it doesn't matter if you've already met Satoshi or not as long as there is one "person", Satoshi (i think) who invented bitcoin and thats the thing that i would focus and say to the one who invented this "THANK YOU".
