Well the red links have a number next to them, the number itself is a link to a page that shows every page linking to that one. Go through them, find the pages that are out of date by a couple of years and start there. Once those are trimmed down, you could put up a blog post or some such to advise against red links or that you plan to clean them up some for more active pages.
