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.
Wow. I've been complaining about a lack of stuff lately, but this week just had a ton waiting for me. The big one, I guess, is Legion of Three Worlds. I thought it was fairly enjoyable for the first issue, but I had some complaints with it.
