I think, we need contribution rank as we have rating rank. I suggest we follow rhythm game model.
For example
- SS: > 100 contribution
- S: <= 100 contribution
- A: <= 50 contribution
- B: <= 30 contribution
- C: <= 10 contribution
- D: <= 0 contribution
We can make the system more generous by following plus and minuses:
- B+: <= 35 contribution
- B: <= 30 contribution
- B-: <= 25 contribution
This will incentivize peopel to make smarter posts also rhythm games are brilliant: 初音ミクが大好きだ
