Say we have a good list of "latest articles" on each pages, which works in terms of user experience, but is probably just a lot of noise for search engines as it changes often, would it be wise to make them non spiderable in some way just to leave the natural main menu? If so what would be the best approach without using cloaking techniques? nofollow? iframes? javascript? I think the nofollow method would work with Google but not so much with the other engines.
