It varies widely I imagine- you can see it on Slashdot very obviously: some stories get 1k comments, others get 50. There is a HUGE variance in interest on stories- and it's not always predictable. But when the planets align, I bet the traffic generated could easily be low 6 figures to a single site, and that would be over 3-6 hours.
