if you are relying only on the lists of topics recommended in the Digests under Resources you will miss most of what goes on here. once you've cruised those lists, wander around in the board (start at the Home tab) to see the rest of the goodies.
you might also give the "Unread Threads" and "New Posts" a try. those lead us to threads we have never looked at before and/or to new comments posted to threads we have looked at before.
