Before you rush off to study it (which I highly recommend, for anyone who has the chance / ability), it's not so much about learning better systems of ethics or learning about the many types of systems of ethics that have been thought up in the past, but it's about learning the arguments why they are/were wrong and how they break down in situations, and to carry these arguments. That's how a lot of fields in Philosophy work, and why it seems such a dry study of "arguing for argument's sake". The point is, by doing this, practice, you learn a lot of useful things along the way and sharpen your mind.

I do agree with the other poster that the featured article (while interesting to read), does seem to lack a bit in how it connects with actual philosophy of ethics.
