Just read some of Nick Szabo's writings in his blog.  One thing I can see is that he is brilliant in many different areas.  His paper on Bit Gold is truly fascinating. http://unenumerated.blogspot.com/2005/12/bit-gold.html 

I think it would be in all of our best interest to just let "Satoshi" remain anonymous though.  If for whatever reason he values his anonymity more than the "bit gold" he created, we need to give him that at least out of respect.  Of course I am curious who this person is.  It is human nature to be that way, but I think the entire Dorian Nakamoto media frenzy should further cement the real Satoshi's desire to stay out of the limelight.  It just isn't worth a free sushi lunch.
