I'm not sure why they'd hypothesize that someone who apparently used Bitcoin only some time after it was widely made public, and then used it in a rather poor manner anonymity wise (the aggregation), was the founder— other than to make headlines like this one. :(
In any case, the address in question (https://blockchain.info/address/12higDjoCCNXSA95xZMWUdPvXNmk...) doesn't belong to Satoshi, it belongs to Dustin Trammell: http://bitcoin-otc.com/viewgpg.php?nick=I}ruid ... who was actually my first guess, and could have easily been discovered by anyone with 20 minutes and access to google. :(
I really can't understand why such a respected name is attached to work of such low quality.
