Principal author of the inaugural 2007 iTest Tournament of Champions and of this year's 2007 iTest, Mathew Crawford has a blog over on LiveJournal that requires a password to view. He made one recent post visible publicly though, regarding an interesting incident he went through recently involving credit scores, an unpaid bill, and the type of clerical errors that occur on a daily basis but end up wreaking havoc on undeserving individuals down the line. Very interesting reading.
