There are currently 32 users who have enough rep to vote-to-close a questions and 3 users who can delete a question on Area51 Discuss but there are a ton of questions that are either not relevant or not useful anymore.
The questions I'm referring to usually fall into 3 groups:
- updates to the proposal description (no longer necessary after the change is made)
- requests to merge (which linger after the merge is completed)
- vote to close proposal (which linger after the proposal is closed)
Most of these questions are only useful in the short term until changes to a proposal are made. Afterward they just linger around as unnecessary cruft that makes it harder for users to see questions that are more current/relevant (such as new requests to close duplicate proposals).
- votes to close a question are only locked in for a short period of time
- The number of users who can actually vote to close or delete a question is extremely small
- As Area51 releases more sites and its active community is shrinking
I think it's necessary to either lower the cap to close/delete questions, or provide a means to dispose of old/irrelevant questions on Area51 discuss.
The high likelihood that most/all of the questions on discuss will quickly become irrelevant means that sufficient facilities need to be added so the active user community can trim the cruft.
