After a (somewhat large) break, I have been more present in the last days. I noticed that many questions are flagged and get onto the Review Queue.
However a few hours or even a few days later, I notice that the questions are not only opened, but stay by 2-3 close votes.
We need 5 votes to close a question. However in a review process, if enough people (also 5, IIRC) vote to leave the question opened, the close votes are discarded and the question stays open.
Yet, those questions stay in-between.
Please remember to check the Review Queue, and decide. You may want to keep it open. Or close it, that's your choice. But it's better to try to take a decision, than staying in an undefined state.
If you need some help, you may have a look at the help.
