That'd certainly put pages linked to from the front knol page up quite high. It does make me wonder what happens when a page changes its outlinks a lot, does pagerank get distributed along the last snapshot or does it amalgamate them. If this is whats driving the high page ranks they'll certainly drop off in time. To preserve their reputation as an impartial index they should make those front page content links nofollow.
