As a business owner I spend a good portion of my time online making sure people can find me and my business online, in fact I am doing it right now by writing this blog. It is very important when you are online promoting yourself and or your business that you share the information people need, and keep your private information like bank accounts, passwords, drivers license info, social security numbers, and mothers maiden names safe. Applications and programs that connect to Facebook, Google or other accounts are especially dangerous because once connected you think that all it does is let you play a game but it is connected to all of the information you have already provided and might be used in ways you don't expect.
