I have been reading the posts about what defines a poor question, and I am impressed at the level of intensity of feeling in that regard, and rightly so. But there's something on my mind: while we are speaking of the importance of good questions in making this a place for attractive to math talent, we must also consider the other half of the equation: good answers.
Too often I see quickly posted, poorly-thought out recommendations which are not really answers so much as fishing for a quick upvote. "Maybe you want to try this." An example of this is here (but I think you need enough rep score to see the deleted answer of which I speak).
The danger of such answers lies in sending a trusting OP down a path of frustration and tears, because such a "solution," though plausible-sounding, is just an impulse, nothing more. That suggestion I posted was one quite obvious looking, and one I spent an hour trying to make work. I am pretty skilled at problems like the one to which I linked; imagine a student working at that? Yikes.
I am not proposing new rules by any stretch. How could I? I myself have posted plenty of poorly-thought out solutions that I have since taken down. But not once have I posted the first idea out of my head without at least working it out and being reasonably sure of a path to a solution, even if my thinking was flawed at the time. My flawed thinking should be evident in what I post.
So what I am suggesting? Maybe an addition to a moral code (if one exists here), against the dual perverse incentives of a) rep score, and b) not giving out full solutions to HW problems. I hereby beg my fellow M.SE'ers: please, do not make suggestion about a possible solution if you have not already tried it yourself. I know this may slow you down and may possibly cause the sacrifice of potential upvotes, but if we are really going to make this site something special (which I clearly think it is), the quality of our answers, as well as our questions, needs to be better. And that does not start with eliminating wrong answers (how could it?), but thoughtless answers that do potential harm.
Thanks for reading this far. May your day be a joyful one.
