In economics, a network effect is the phenomenon by which the value or utility a user derives from a good or service depends on the number of users of compatible products. Network effects are typically positive feedback systems, resulting in users deriving more and more value from a product as more users join the same network. The adoption of a product by an additional user can be broken into two effects: an increase in the value to all other users and also the enhancement of other non-users' motivation for using the product.
Stamp collecting is the collecting of postage stamps and related objects. It is an area of philately, which is the study of stamps.

However, some people do interact with virtual economies for "real" economic benefit.
In economics and law, fungibility is the property of a good or a commodity whose individual units are essentially interchangeable. In legal terms, this affects how legal rights apply to such items. Fungible things can be substituted for each other; for example, a $100 bill (note) is considered entirely equivalent to twenty $5 bills (notes), and therefore a person who borrows $100 in the form of a $100 bill can repay the money with twenty $5 bills. There is no requirement to return the same $100 bill. Non-fungible items are not substitutable in the same manner.
