I'm not complaining why my question is closed. Let's just say that some people think that it should be closed, and one of those people happens to be a mod. Since the mods don't need to vote to close on a question (because the "vote" will effect immediately), should they do this?
For obvious reasons to close a question like off-topic or too localize, I think the close from the mods is quick and agreed widely. However, the unclear reason might not be agreed on mass. Some will agree, some will disagree, and that's why we need to have the poll to see whether it is unclear or not. If they "vote" too soon, the good-will of the mechanism will be broken. When vote to close a question, the mod should represent themself as a user of a community, not... a mod. Therefore, if needed, the mods should wait after 4 users to vote before take it down.
