Many sites have the ability to bring up info about almost any individual. I find this to be a very useful tool. Was wondering what steps I need to take in order to perform the same tasks these site offer for a price, for free... Where should I start learning how to data mine like the pros. Also, can this be done with tutorials, advice, Sites??? And if so which ones? And also wanting to know techniques about speeding up the entire process.


P.S. How exactly is data mining to be well performed? Some hacking? Need Help there for sure.
