Using money to illustrate the point of this and about the value of technology, US dollar is just one of the currency that may be used to as a medium of exchange. A US dollar is actually just a piece of paper. What gives value to a US dollar is the ageement by many parties that it can be exchanged with something that actually provides value to the person who own the dollar. That is, the value of the dollar is not in the dollar itself ( to most people), but in the item that it can be exchanged with. A US dollar is just one of the medium of exchange that may be used to obtain something of a real value. Likewise, a web service is just a technology that may be used to implement a service. A service by itself does not hold any value. The value of a service is in the capability that it may provide real world effect that is of a value to the person using it. :-) H.Ozawa
