IMHO the question is, to a huge extent, moot. Users can easily bookmark their favorite starting pages in a myriad of ways; I don't think the login page should be a place for us to guess what the most likely ones are. In fact... I think I've just convinced myself that the NN link should simply be removed. But if it were changed from NN to RAT, I wouldn't mind terribly. I never use that link. :-)
