Closed questions on Web Apps SE are almost never reopened by regular users only:
Only 1 question got reopened in all of 2023 without moderator help. TheMaster Oct 30 at 10:16
One of the reasons is the tiny number of active users with 3k reputation point, which is the current threshold for regular users to be allowed to cast a reopen vote on a closed question.
Catija mentioned the following when they were a CM:
We will only adjust individual reputation levels if the current number is not working.
The current number for the reputation threshold to be allowed to cast a reopen vote on a closed question is clearly not working, since as mentioned above, only 1 question got reopened in all of 2023 without moderator help.
Therefore, I'd like to make the following proposal: let's reduce the reputation threshold to be allowed to cast a reopen vote on a question, so that more regular users can participate in the reopening of closed questions.
According to Henry.Ecker's SEDE query on How can one see how many regular users cast at least one reopen vote during the current year?, only 5 regular users with 3k+ rep cast a reopen vote in 2023. They cast a total of 10 reopen votes. This statistic ignores reopen votes that didn't result in the question being reopened (there seems to be no way to gather that information).
