With the SO community growing, I see more and more frivolous closings. It's natural considering the number of potential close votes is increasing, and the number of close votes required is always exactly 5.
I think that's only part of the problem -- the more hidden issue is that people seem to throw out close votes mindlessly sometimes. I can imagine a few theories:
- Flaunting their ability to use the close vote system
- People may see it as a structured way to downvote. It's a way to downvote and choose the reason via a fixed list.
- The close voting system is so intuitive that it can be a knee-jerk reaction. For example if something is just arguably on topic, or where an answer could involve subjective reasoning in any way, users may click that close button instead of giving the benefit of the doubt.
I am not sure it's a problem worth solving at the moment, but is this flag being raised? Is this what is desirable for SO? I think you could make the argument either way actually.
On one hand, we want to embrace interesting questions even when they press the limits of being on topic or answerable.
On the other hand, bigger community means we should be more discriminating with questions. I'm just not sure the same old close voting system accomplishes this in the right way.
Edit: continuing the investigation of @ConradFrix, here is a graph showing the average score for closed questions (in red), and the average score for all questions (blue). The data is strange; basically for a long time the closed score was actually higher than the average score.
It would suggest that my observations do not represent the trends of the site, and that as time goes on, the opposite effect is actually happening: Lower percentile scoring questions are being closed, at the same time that a higher % of questions are being closed.
I am pretty sure that if we added a "Close votes per user" and "Average Rep of Close Voters" -- to try and visualize "close vote quality & diligence" we would see an increase over the years, meaning the watchdogs of the site are being more and more diligent in closing questions, which would then indicates frivolous close votes are not happening.
I'm not curious enough to add those metrics to the query.
