One trend I've seen since the improved flagging feature was rolled out has been users—who are otherwise able to vote to close—instead opting to flag a question for moderator attention with the standard close reasons like "low quality", "not constructive", "not a real question", etc.
We moderators do take a look at every flag that comes in, but we try, as much as possible, to defer to the community's actions when it comes to closing a question. While we will close the clearly off-topic or not constructive questions, we're more likely to leave a borderline question open if it hasn't received any close votes.
So, before you flag a question for moderator attention, please consider doing one or both of the following:
- If you have the reputation, vote to close.
- If you don't have the reputation, or even if you do have the reputation, leave a comment explaining why you don't think the question is a good fit for Programmers.SE.
These two actions send a signal to us and other members of the community of what you think about the question and increase the likelihood of what you're trying to accomplish: that is, keeping Programmers.SE a useful resource for constructive questions about software development.
