The Workplace's question close rate has been oft discussed on meta here. If you've been around here more than a few minutes, you probably are aware of all the words written on the subject, opinions, and walls of text on the subject.
This isn't going to be one of those. Instead, it's a challenge to us collectively as a community.
Let's edit/reopen more questions.
If each of the hundreds of us who have received 1000+ reputation this year edits a single question a week to make it on topic, we can easily make these numbers for the past 90 days(taken from the 10k user tools, boxes mine):
Let's collectively make these look different in a positive way. Right now, a reasonably small percentages of closed questions are edited at all (the first column) and often when they do get edited, they don't get reopened.
Even assuming some questions are not redeemable through edits, there are a lot of possible questions.
After 90 days, we can checkin again and see how we're doing (this happens to be January 1st of 2019).
In closing, while there are a ton of meta posts I could link to, I'll link to jmac's post from years ago which is just as relevant now as it was then.
Logistics
If you find yourself making an edit specifically for this purpose, go ahead and add it as an answer below. Once questions are reopened, we can clean up the answers (either you or us as moderators) and keep the list of answers questions currently needing eyes and also make it more obvious when there is an edit associated with this effort.
We can keep the questions (as answers) here until they are non-negative in voting, too, if that applies.
