I saw an article referenced on the Wall Street Journal's webpage and found the analysis to be interesting (but that may be because I am a dork). Basically, they use the frequency each columnist uses specific, unique words and then apply that to individual columns to see if they can determine the author of the different columns.
I think the most interesting part was the list of the top words and adjectives/adverbs used by each author.
Just to start this off with a bang, Kevin Spacey has signed on to play LEX LUTHOR in the SUPERMAN movie... it should get the official announcement over the weekend. BLACK PANTHER returns early next year with John Romita JR doing the art.
