The accepted answer to the Meta post When should I vote to delete a question? advocates an aggressive approach to deleting closed questions.
Summarizing, the author suggests:
- always deleting unclear questions
- near always deleting off-topic questions
- deleting too broad or opinion-based questions that attract poor answers
- sometimes deleting duplicate questions "if the duplicate does not add terminology or alternate phrasing to find the question."
As of this post, there are
- 891 closed/non-duplicate questions
- 893 closed/duplicate questions
It seems like decluttering by removing more of our closed questions would be yet another way to improve finding answers on the site (along with editing and retagging open questions to ensure they are accurate and easy to find).
I'd very much like to know the opinions of both mods and non-mods alike.
UPDATE: 5 May 2021
I've nominated four questions for deletion, to see how the community decides on them. My criteria for choosing:
- opened before 2017
- having no answers
- fewer than 100 views.
The idea was to identify questions that are not contributing to the site, even as guideposts to the kinds of questions we close.
- Weird crescendo that looks different [closed]
- What is the style of song in this video and where can I find the entire version? [closed]
- Any information on this tease of a fugue in Beethoven's Hammerklavier? [closed]
- Help Tabbing Short Guitar Segment [closed]

The Meta post Can closed questions be found on Google? (the answer is yes) reinforces the idea that pruning (i.e., deleting) closed questions is a good idea. If kept around, "bad" questions will be found in Internet searches, promoting additional bad questions.
From the accepted (and only) answer:
[Finding closed questions via internet search] is helpful in the case of questions that are closed as duplicates, since we keep those around as bread crumbs to the canonical reference.
Other than that, "closed" usually shouldn't be the final state of a question. Some closed questions can be improved to the point where they can be reopened, and others should be deleted.\
This dovetails with the issue brought up in Are answers to off-topic questions worthy of downvotes and/or flags? — off-topic questions that show up in a Google search, and which also have answers, will even further promote such off-topic questions.
