I check the site many times a day / evening. I'm always logged in, and I always start at the main index. I go by the slice icon telling me if there are new posts in the categories that I care about. The sections that interest me the most, like Neapolitan and Hearth Ovens, I read everything that's posted unless it's proven to be either so technical that I'm not interested (some of the build threads) or contentious (when the boys are having a pissing contest and that doesn't interest me). I also check the equipment and ingredients boards, New York, General, Chitchat, News, Reviews, etc pretty often but don't read every thread in those, and the rare occasions that there are posts on Dessert, Specialty Grains or Monthly Challenge, I'll always read those. I don't ever check the boards that hold no interest for me, like Chicago, American, Cracker, Thick, etc, and I just leave the slice icon up on those, because I don't bother to mark stuff read if I don't care about the category. So I guess the most important navigational tool for me is the slice icon telling me which categories/threads have new posts, and then being able to click "last unread" to be able to start where the new posts do.
