Great article! I've sent your bounty to the specified address and you can track the transaction at:

https://etherscan.io/tx/0x5151ea8ee14bc61207fb251f7331d0dceec3be4ce6a00b8e5d55a74de53af82a

Note that the ethereum network is going slowly at the moment, so it may be a bit before the transaction shows up, but it will as soon as the transaction is ready to be confirmed.
