Saw this article about a system that can help you decide on your next decision. The system is called Hunch.
What interests me is the potential for others to exploit the system. If there is a specific pattern for Hunch's ability to predict your decisions, and utilizes the info from Twitter (or potentially any other social medium), others who care enough, can utilize it to predict an opponents strategy.
Your own decisions are no longer secret. Its scary, or really interesting, that this can be automated.
(Although I must admit, I am not a believer in any system that profiles an individual. If a person knows he/she is being profiled, they can simply act differently.)
So next time you feel an Ad or consumer product pitch really hits home, to you personally, you now know why.
