Seems like it would be not unreasonable to have some sort of aging built in. Since I suspect reputation is a major factor there utilize all votes for rep, but for answer relevance gradually reduce the impact of votes based on their age. There'd probably need to be a way to mark 'evergreen' or perhaps 'stable' answers where that decay would be slower, or simply allow people to (with limits?) go back and refresh their votes on articles. Separating historical reputation from answer relevance ranking would be an attempt to reduce the perceived value to individuals of tampering with scores - refreshing a vote on an answer wouldn't impact overall reputation.
