I think there's a pretty good chance Adam Back is Satoshi, but I don't think this is a great article. Perhaps he's rendering a careful scientific process in a way that makes for a readable narrative, but as written, it sounds like a lot of gut feel and confirmation bias.

The biggest new contribution to the Satoshi question seems to be ad hoc stylometry. To have faith in his methodology, he should be testing it on identitying other people. If he were to show me that a repeatable methodology that doesn't require hand tuning can identify other people with low error rate, and it said Back=Satoshi, that would be much more convincing.

Like so much tech writing done by non engineers, there are many places where mundane things are made to sound remarkable (e.g. Black's thesis used C++, the "heated debate").
