Methods that map to GET should not change any data. Putting links to other resources in your responses makes it easier for clients to follow a chain of data. For example, if your service returns a collection of resources, it would be easier for a client to access each of the individual resources using the provided links.

If links are not included, a client needs to have additional logic to follow the chain to a specific node. Requiring the client or the service to maintain state information forces a tight coupling between the two.

Tight couplings make upgrading and migrating more difficult. Maintaining state can also make recovery from communication errors more difficult.
