Why I ask was triggered by this question, but I have witnessed the same pattern often enough, so now the proverbial barrel is full and overflowing.
Basically, Wyatt certainly knows the other question and its answers, being a very curious user who isn't content with superficial answers. Or needs to be helped along every step of the way. I see evidence for both. Closing the new question and referring him to older answers he has all read will not be helpful to him. If the new question helps to gain a new angle and interpret the old answers better, why not let him have his ways? Maybe more people will have the same question?
I don't mind careful purging, but maybe we should wait until some more time has passed for the new question to collect more votes and answers and we can see better if it is worthy to be kept. Half a day certainly isn't enough.
