I read a post here recently (sorry I can't find it), where the issue of a high increase in low quality questions was brought to our attention. I have a final coming shortly, so there is a question I would like to ask (graduate measure theory) but I don't really think its beneficial to everyone. Would it be best to ask this and delete it afterward, or should such questions even be asked. Just to establish what I consider a "dumb question", I would like to ask why the intersection of monotone classes that contain an algebra is still a monotone class.
You can only delete your question if it has no upvoted answers. If it has a valid non-upvoted answer and you delete the question then you will find yourself under a bit of a microscope. So no, you should not do that. The number of low-quality questions sitting around is an issue, but not nearly as big an issue as the rate at which they come in. Do not take this as discouraging you from asking your question. Please do ask it. If you ask it well, no one will complain.
