The only thing I am not totally sure is the report by curators thing. Do you propose this report would be posted in a separate post or in the comments of the said post. I think, personally, that it should be posted in the comments section and be as brief and concise as possible. And I also think it should be done for the posts upvoted 20/20 as they are truly the ones who could use the help. I know this is more work but it can be as much as three bullet points per post.
I agree with what you said. The reports were to be put in comments (too hard to track and messy otherwise). For the 20/20, this may mean too much work for a small team of curators. We have several ways to go over that, the two natural ones being involving HM (as proposed here) our increasing the size of the team (considered but not proposed for now). Anyways, we will move forward and we may need to retune at some point. But we will try to do something.
Maybe an interesting proposal would be to go more in depth about the posts that are highlighted every week in the "digest" and why they are good.
