The /review
page displays questions matching the following criteria:
- first answers from new users
- first questions from new users
- late answers provided by low-rep users
- low-quality posts; I don't know the quality algorithm, but it presumably changes rarely if at all
EDIT to include info from comments:
If I understand correctly, the posts listed under all of these categories will never change. That is, once a post is added, it will never fail to meet the criteria (unless it is edited, which is rare). The posts listed in the last category will never change. The posts listed in the others will eventually disappear as the OPs get more rep. (That seems like a flawed system to me, though; a user's first post doesn't automatically improve just because the user got better after writing that post.)
As a result, the number of posts listed on the review page will increase steadily over time, while the percentage of posts that actually need attention will diminish. To resolve this issue, we need a way to get non-problematic posts off the list.
EDIT to merge in the contents of a duplicate question:
There should be a "mark as okay" button that will remove valid posts from the review page. It could require a number of users (three?) to click it before the post is removed. This will clean up the question list and thus make it easier to review.
