This sounds good at first: a citizenship "score" could become an integral part of your profile, maybe on the same level with reputation. It could be a way to award those who put a lot of time and effort in cleanup / quality control in their tags instead of just accumulating rep.
However, looking at how even the prospect of getting a fricking badge leads to widespread abuse of the system (votingvoting, editingediting), it's a very real danger that this would become just another number you can increase through harmful actions like random voting, or approving BS edits.
I'm sure Rosinante's approachRosinante's approach is shared by many community members: we often already check out users before we answer a question. How invested is this user in the community? Did they bother to register a user name? What kind of contributions do they make? Do they answer questions as well? I tend to be much more willing to help fix an imperfect question when the OP has a track record of answering questions, or shows a real interest in the community. How about instead of creating another metric, making the existing ones easier for us to look up in the user's profile?
Maybe even in a separate "citizenship" tab, designed in infographic style.
We could display....
Definitely:
- Successful close votes (ie. votes cast that lead to a closing)
- Helpful flags
- Question / Answer ratio, or maybe even better: answer upvotes
- Number of comments
- Some of the "hard" badges, maybe those that are displayed in the pre-election stats
- Meta participation
Maybe (I'm unsure about these because they are so easy to game):
- Voting
- Edits
That would show us all we need, but without the problems of a new metric.
