Probably the easiest way to do some of this would be to find some way to extend the depth of best nodes so that the best nodes of all time could be made a longer list (perhaps via something like "read more").

The other obvious thing to point out is that plenty of gems will still be missed, because there are plenty of times that the good stuff is overlooked by the masses. The only real way to find the good stuff on a given topic is to look for it, ie, ask in the chatterbox or super search.
