First: "Low quality" is subjective, and the usage in this question is based on my personal opinion. The community and every member thereof is free to agree or disagree on this judgement. I stress that my judgement expressed here concerns the posts, not the poster. A single user is behind many of the problematic posts, but they have also contributions that I consider very valuable.
We have had some low-quality etymological questions. Here is a good recent example. More of them keep coming in despite attempts to help. It is not a horrible flood of such questions, but still a pretty consistent flux. As high-quality content is important for the prosperity of our site, I see this as a problem. Question 1: Do you think this is a real problem? Such questions have attracted some downvotes and flags, but I don't know what the community at large thinks of it. Please do not be afraid to express it if you disagree with me; an open and civilized discussion is always possible. If there is no problem, then the discussion ends here.
It's a basic problem of the StackExchange design that there is no clear course of action for low-quality content. Many of the badly written questions are on-topic: they ask about the etymology or meaning (or shift thereof) of a Latin word. (If the question concerns the meaning of words in French or English with no connection to Latin, it is off-topic.) If such questions are to be ruled out as off-topic, we have to redefine our scope accordingly. That can be done, if we just know how to describe the restriction to be added. To enforce and communicate any new scope restriction, we can have a custom reason to close questions. But I stress that this is only one of many possible courses of action, one of them being doing nothing.
Question 2: If you answered "yes" to question 1, what makes it problematic in your eyes? The way I see it, the issue is not with the topic of the question, but with the way the question is asked. I can't find a good way to put this myself, and others can see the issue differently.
Question 3: What should we do? There are several options, not mutually exclusive:
- Do nothing.
- Vote down the questions that you find bad. Automatic question bans are triggered if a user asks too many badly received questions. (But be careful to vote based on the individual merits of each question, not on the user asking!)
- Edit bad questions to improve them.
- Find a wording to describe what is wrong with a common type of low-quality questions, and incorporate that to our scope. (There are attempts and ideas in the linked question about closing reasons.) The way I see it, these questions are not off-topic per our current definitions, but definitions can always be updated to reflect the views of the community.
- Something else.
I will leave comments below if you want to leave a quick anonymous answer to question 1. Written responses in the form of comments and answers are very welcome.
