I personally believe that first of all there is no hard and fast rule. I have some applications that log a LOT, in and out of methods, and status updates through the middle. These applications though are scheduled processes, run hands off, and the logs are parsed by another application that stores success/failure.
I have found that in all reality, many user applications don't need large amounts of logging, as really if issues come up you will be debugging to trace the values there. Additionally you typically don't need the expense of logging.
However, it really depends on the project.
