Bitcoin payments are irreversible, just hope that satoshi read this and send your coin back to you
Sending a large chunk there and claiming it was an accident would be a nice attempt to see if Satoshi is monitoring this forum!
I think Satoshi might be fine with the ruthlessness of the protocol as in: "If you can't type a number right, maybe someone else should get the power your money represents".
That said typing wrong is my nr. 1 fear with BTC...
