The way I think of it is by going back to how PG once described HN as YC's university campus. Like a college campus, people come through, some stay, some leave. Each new class has to learn some of the same lessons... hence some history, and some classes/topics, repeats with predictable periodicity.

Doesn't mean it doesn't bug the old hands to see the same thing come through again and again. :) And links to old discussions occasionally dig up useful old learning.
