identification-question has always been main attraction of pain and discussion. So to handle them properly Fourth off-topic close reason has been implemented. This is helping. But the time for closing is different.
Some questions get closed within an hour, whereas some remain for more than 24 hours waiting to be closed. In some questions, comments asking to add more detail are posted and in some they aren't. This question is an example. The user traffic does play role how fast the question get closed.
So how long should we wait or it does not matter, identification-question does not want to get involved in this messy part?
