Do you believe Satoshi was a pseudonym used by more than one person that's why there's differences in written English ?
Well, this is very interesting to discuss because I personally believe that Satoshi is a group of anonymous people, not one anonymous person...
I still remember very well someone once said that 'it is not difficult to detect the presence of one person but when there are many it will be very difficult'. satoshi is a group or individual, I still admire him and really grateful for making the world a better place.
