Questions shown in the staging ground appear in the top questions and similar pages. I don't necessarily disagree with that as it could be a good way to fix the scaling issue in principle.
However, I have one big issue with this: People browsing questions (even with 500+ reputation and having asked questions before) don't know how the Staging Ground works.
For example, I have seen a user asking for clarification in the Staging Ground without using the Requires Major Changes
option and asked them to use that option in the future. As a response I was told they were just browsing questions and didn't know about the UI. They also posted about this afterwards (thank you a lot for your insights). This user is by far not the only one with that issue bringing me to this request. Until now, I have messaged >10 reviewers about that via https://chat.stackoverflow.com. Out of these users, >6 responded. Most of them were saying it's related to the Staging Ground being new/not knowing how to work with it in some form or the other (and the other one was confused/stopped by the locking system). They just didn't know better and were thankful about being corrected.
Please, make sure that reviewers are explained how the Staging Ground works before they are reviewing their first question, commenting or closing it, especially for reviewers that get to the Staging Ground using the top questions page or similar.
For example, I could imagine users getting some information on how the Staging Ground works along with the reviewer guidelines when they view their first question in the Staging Ground.
I could imagine this being in the form with a modal shown when opening a Staging Ground post the first time. This should include:
- What is the Staging Ground (a place where askers can get their questions improved before them being public)
- How to review questions
- This includes the reviewer guidelines or at least a link to it
- Explain that reviewers should select an action (like "Requires Major Changes") when reviewing a post as opposed to just commenting
- Tell (especially higher-rep) reviewers to prefer "Requires Major Changes" over closing. If a post can be improved by the author so it would be considered fine for the site, it should probably not be closed in the Staging Ground.
Alternatively, I could also imagine the Staging Ground not appearing in these question lists by default and only showing up there once the user received some onboarding by viewing https://stackoverflow.com/staging-ground once.
This way, we would still get a lot of reviewers seeing Staging Ground posts in the question list and these people understand how it works.
