Just read it. Seems really strange that all these emails would "leak" and Craig would be emailing people with the Satoshi email.
I know we have developed the "myth of Satoshi" and Craig seems to shatter that, but it is not based on nothing. Satoshi seemed to be a very private person and very good at covering his tracks. I doubt he would be emailing his lawyer and others with an email that can link him to his pseudonym...just seems sloppy.
The reason a person like Nick Szabo makes more sense as Satoshi is that he acts the way we would expect Satoshi to act.
I have the same doubts too.
Overall, it seems like a well orchestrated plan to make at least a part of the bitcoin crowd believe he is Satoshi.
Edit: One thing I didn't pay attention untill I read some comments is that the article is referring to the last December.
(I think I've somehow skipped the first lines of the article and focused on the header/subtitle where is a misleading "Yesterday 8:10am")
