Giving Away Information for Free

If you are doing it solely because you expect people to do something in return for you, then i would say it is not good. That is much like basing a friendship on the idea that you serve some need for me, so i want you as a friend. If you stoped serving that need, then we're no longer friends. Even though we may be giving away information for free, with the idea that there is a possibility of getting something back in return for doing so. It's all about helping people right from the beginning.
