Sometimes this can help, but lately I've been running into the opposite problem where people have been following this advice to such a degree that one cannot ever figure out what is going on without having to constantly jump around to find the actual code involved in doing something.
Ah I hate that, too. It speaks of bad abstraction, over eager abstraction or unnecessary coupling that is the hidden behind this. Difficult to fix though without essentially starting over.
I absolutely agree that method extraction can be abused. One should not forget that locality is important. Functionnal idioms do help to minimise the layer of intermediate functions. Lamda/closure helps too by having the function much closer to its use site. And local variables can sometime be a better choice than having a function that return just an expression.
