I have recently been reflecting on my voting patterns. The discussion on this answer suggests that different people have different views on downvoting. I thought it would be good to figure out what the community thinks should be rule-of-thumb guidelines on downvoting.
I usually downvoted questions if they are poorly written and show little effort on the part of the asker (and if there was edits made to improve the question, I would cancel my downvote) or if I think they are out-of-scope for cstheory.
For answers I usually downvote if they don't answer the question or if they are incorrect. However, I sometimes downvote answers to a homework question, especially if its a homework-level answers.
For answers on community-wiki questions I vote much more aggressively, sometimes downvoting something if I don't agree with or the answer is not insightful (especially for big list questions).
I thought this voting strategy is reasonable, but looking at the stats suggests that I downvoted a lot more than everybody else. In particular I think I have the highest total downvotes (~99) and one of the highest downvote percentages (~10%). How should I adjust my downvoting?
Also, there is some general downvoting differences between our top 20 rep users, and the MO top 20 rep users. In particular, it seems MO is more willing to downvote:
% down | MO | TCS
0.x% | 4 | 7
1.x% | 1 | 2
2.x% | 2 | 3
3.x% | 2 | 2
4.x% | 4 | 2
> 5% | 7 | 4
That might mean a difference in convention or cstheory just has higher quality questions and answers.
What are the conventions and norms for down-voting on cstheory?
