I am not sure this is an authentic way of finding someone or not but I found this interesting.

"By taking Satoshi’s texts and finding the 50 most common words, the NSA was able to break down his text into 5,000-word chunks and analyse each to find the frequency of those 50 words."

* How the NSA caught Satoshi Nakamoto.

I am very sceptical about this kind of research/investigation. What's your take on this? Do you think we can find out real Satoshi with such method?
