I don't think Nas is San.  Knowing San, Nas's online behavior just does not jive with his.  But then, San could have this wildly different alter ego (think Fight Club) and I could be totally wrong.

Having said that, Nas really does not bother me.  His Sajha persona comes off as a flaming pervert, eccentrically paranoid who sees conspiracy everywhere, and more of a dumbass given his "birther" rantings.  But then, there are many more folks here in Sajha who come off as so downright despicable that I find Nas as much milder character.  Anyway, this is an online forum full of anonymous users.  So who cares?
