Did you adjust for time spent on site and/or bounce rates? I've found this kind of temporary traffic burst from high-profile sites is often very transient traffic, people clicking on a link out of curiosity because they saw it somewhere, with a very high bounce rate. It's the kind of traffic from people who open 30 tabs and then briefly visit each one. Doesn't matter (at least for my sites) whether it's Reddit, Slashdot, HN, an NYT Blog, etc.—almost never has the same CPM as "regular" traffic, regardless of the burst source. Visitors who come via organic search or bookmarks are much more likely to spend more than 1 second on the page and read/interact with something.
