Apparently, Twitter is all aflutter with comments about how her hair dryer blew out the power during the Superbowl. (Actually, this happened when I was on my honeymoon and my wife blow dried her hair!)
But I digress. Several years ago I applied for a job with the National Basketball Association. It would have been a bear of a commute had I gotten a job offer. Nevertheless, I was very much interested in the job because it involved an aspect of redundancy I never thought of before: broadcasting. It's bad enough to have a lack of continuity during a game, but it could be an unmitigated disaster if it happens while trading.
So, redundancy is good. Super redundancy is even better.
