Without resetting (or some such technique) then comics that collected lots of votes/hits from long ago would dominate the top of the list and newer comics would have an unfair disadvantage. This way, once a month everybody starts out equal again and each month they get an opportunity to compete from the same starting point.
But maybe instead of resetting to zero, it would be better to use a 30-day, 60-day, or 90-day rolling average, recomputed once a day. There are other algorithms that could be used that give more weight to newer votes and less to older votes.
