I still think overall points are fine. Even if a person does as Gail suggests and answers the QOD the next day after then answer is published, and assuming that every questions is worth 2 points (which they all aren't), that's about 250 weekdays per year * 2 points per question = 500 points. That's a lot of work to try to beat the system, with a disproportionately small return.
