Refereeing papers is something every PhD student should be doing, as soon as they get the chance. It really helps you see the other side of the coin, makes you feel part of the scientific community, and hopefully does not give you a power complex or a platform for revenge --- but I am straying back into ethics again! So, how do good referees do their job, who are they serving, what is right/wrong with the current system, and when are you going to finish that peer review that is sitting on your desk? Also, I have some words of encouragement for those who are presently nursing a wound from having their papers demolished/rejected/discarded/overlooked.
