I often come by questions that are closed because of lack of context, but that still have good answers. It can be questions that contain nothing more than
What is this integral $\int \ldots dx$?
or similarly, which are reasonable to close, but that one or more people still gave a good answer to before the question was closed.
When an open question has a good answer, I am less inclined to close it, and when a closed question has a good answer, I feel more inclined to reopen it for three reasons:
- Since the OP has already received an answer, it is less likely that any further context will be provided.
- Out of respect for the time put into the good answers.
- The answers are a nice addition to the material of MSE.
Is it ok to reopen a question without context, or even a poorly asked question, if it has good answers?
