Ah, that would makes sense. Happens to me all the time when I leave HN pages open for a while then try to use them later. I imagine the bots try to follow links they picked up earlier a long time later as well at times. Kind of funny a bad session system on a site can kill your search rankings, though. It would be fatal for sites that live off Google traffic, and tough for people using off the shelf software to deal with.
