If one has a a very busy site (100K page views/day for example), with many posts published every day (10-15) what do you think of the idea of going in every few days and resetting the plugin to keep the "Also viewed" data fresh?
I'm thinking otherwise that posts published a couple of weeks back that had many visits would accumulate such a high threshold of "viewed next" links at that time that as new visitors hit that page they'll be seeing a snapshot of what people viewed next that's out of date.
Does that make sense?
Awesome plugin, really love it and the concept!
