I think this is a good question. There is definitely a capriciousness to EoQS, that does not seem to be acknowledged by Moderation:
EoQS: The goal is to have a repository of high-quality answers to good questions. So post answers only to good questions, we don't want to encourage a barrage of low-quality questions on here, that's bad for the site!
EoQS: By the way, duplicates should not be re-answered.
Many A User [certainly myself, and going by what I have seen on here, other people]: Wonderful, so we are going to be doing more to stop the barrage of remedial 'hold-my-hand'-type questions we see at the heart of every semester? As you can see from my last thread on here, I'm tired of seeing yet another question coming on here and asking, say, why $\{(x_1,x_2) \in \mathbb{R}^2; x_1+x_2=8\}$ is not a vector space!
EoQS: No MSE is for questions of all levels. The person asking just needs to provide context. You elitist.
MaU: So, if the student just says the question is for class and provides an attempt at a proof that is really just word-salad, that makes the question OK?
EoQS: Sure. Isn't it clear, they provided "context". I don't know if anyone has really defined it, but it's like pornography, you just know it when you see it. Right?
MaU: But...those questions are really duplicates too. There were some otherwise much more interesting questions that were shut down for being duplicates you know.
EoQS: Well just answer in the comments. As everyone else is doing. Can't you see, the goal of MSE is to have a repository of good questions with high-quality answers, and a bunch of lesser-quality questions with answers hidden in a confusing stream of comments is totally in keeping with this.
EoQS: Oh yeah, I saw a bunch of your past answers. Just last week you answered a question that turned out to be a duplicate of a question that was asked and answered in 2014. You also answered a couple other PSQ. You know, questions without that 'context' thing.
MaU: But, I spent a lot of time on my answer to the question that turned out to be the duplicate, and I thought it was well-written and provided a slightly different take. And besides, at this point isn't about every question a duplicate really? I came here to do math, not chase down references. The other questions were just sitting there with upvotes and no votes to close and a bunch of comments, and so it looked like the question was sticking around, I answered it, thoroughly and cleanly too. I thought the goal was a repository of high-quality answers to good questions?
MaU: I also have a lot of well-written answers to a lot of questions on here that turned out to be non-trivial too.
EoQS: Doesn't matter. Into the corner, you Low-Quality Contributor!
Too much truth in the above indeed. There is too much ambiguity--and nonsense--into what constitutes a good question on here. And then besides that, there is nonsense in how a supposed low-quality question is supposed to be handled. Which makes me think that EoQS as is right now doesn't seem to do much, except weed out some really smart users who have contributed a lot to this forum. If I am wrong, then answer me this: Is anyone not a moderator that happy with how EoQS is going?
I'm NOT implying that Moderation is evil or incompetent, I can imagine running this site is actually quite a challenging and oftentimes thankless job. No matter what you do, you're bound to get some heat for that on here, especially because human nature being what it is, people speak up more when they are disgruntled than they are when they are satisfied. I do think it is hard to strike a good balance between quality-control, and having a lot of activity on here. BUT, the current EoQS does seem to have consequences--unintended or not--that many of us find problematic. I do hope that some things about that are being rethought.
