It's unlikely a large dev team would be able to keep this secret. The code was also very consistent and not that large of a code base. It reads to me very much like a single person wrote it.
The other oddity in the code is that there is a mixture of US/UK spellings being used, which also suggests more than one person.
Oh, and the pizza thing is another myth, the real monetization was the liberty exchange setting up as market for $/bitcoin exchanges.
Not an oddity are all, it suggests a non-native speaker. US/UK spelling inconsistency is rather common unless you went to school in one of the two.
Maybe he is just canadian. We use a mix.
It looked nothing like academic C++. It was also very small. Some people accuse it for being "messy" because it was highly coupled and non-modular. But that would have been premature and would have increased the size and complexity dramatically. Its lack of modularity was mostly reasonable for its level of complexity, and had Satoshi tried to make it modular he probably would have created boundaries that would have needed to be thrown out later.
When I first got into Bitcoin I just read all the code. I know plenty of other people did too, that wouldn't have been half as reasonable had had been broken into a lot of parts with interfaces between them.
First time I read this word and there seem to be no positive results for it on Google.
