What is money? Until a person realizes that money is anything of value (perceived value) that can be traded for something else of value, he has a mistaken view of what money is.

Where is the money exchange between us as we use the computers and this forum? It is in the value of the things that we say in our posts.
If you don't think that your posts are things of value, then why do you post them? But if you think that they have value, recognize that you are trading in money in a simple conversation between members... value for value.
