I always wished the decay with time was normalized by the number of visits someone makes per day. That way, when someone visits frequently, they're often see more stuff, but if someone only visits once a week, they'll see the highest rated stuff over the past week (and some lower rated stuff from the last few days). Perhaps not completely normalized by number of visits, but at least nudged a little by number of visits, to produce the user experience mentioned in the above paragraph.
