I never thought about that. I actually think this is a great idea. One big issue is a lot of people would be upset at the idea of their reputation getting smaller. Maybe have a new "influence" or "helpfulness" score along with reputation that takes into account the decay you are talking about. Or maybe just have a different scoring mechanism altogether based on how knowledgeable and helpful your are to the SO community.

I have noticed that it is common among the high rep users to say that the reputation doesn't matter, so this would put their claims to the test.

Perhaps a "Wisdom" stat that's influenced, in part, by the age and positive signal of substantive reputation that's old enough to have decayed.

There's already an "impact" score on your profile, though it seems to just be a rough count of pageviews on your answers.
