You ask what problem would be solved, and then give an instance that I think it would be least effective for. Well here are a list of problems that I think this would be good for.
- Make it harder for someone to distort the system with vote-bots. And if someone wrote a better bot, make it possible for someone other than vroom to get an idea who some of the bots probably are.
- Fairly frequently we have people who say, "What didn't people like about that node?" They want feedback, but the current system keeps them from getting it. The best anyone can say is that people vote for all sorts of reasons. Well this would provide a way to get that feedback.
- Some people use the anonymity of their votes to snipe at others and vote indiscriminantly. We often call this "personality voting". Often the personality votes come very fast. This would reduce that abuse.
- Periodically monks have become frustrated at being completely powerless when faced with voting abuses. This would give them a fairly low-impact tool (compared with merlyn's "Other Users" snapshot anything is low-impact) for doing something. Not a very effective or powerful tool. But something is better than nothing.
Now one point I should make. I structured the proposal explicitly with the idea that the vast majority of your votes remain anonymous, and of the fraction that do not remain anonymous, you get considerable choice. I think that the privacy issues are preserved. What has changed is that there is some accountability for the "faceless hordes". Is that worth potential for conflict that comes with accountability? I think so, but then again I was on the wrong side of the current system right at the start, and in every case where it has been argued, I have been on the side of making things more accountable...
