I'm curious: how are we supposed to handle questions that have been changed such that older answers no longer reflect the questions being asked? In the context and spirit of this meta question what do we do for (or to) existing questions who've been edited such that answers:
- are invalidated
- are out out of context
- are answering questions no longer present.
Here's an example of the 3rd case (which I answered yesterday). The highest rated answer at the moment, Motosubatsu's answer, answers a third question which has since been edited out. Personally I like his answer to the 3rd question, but was confused as I had not seen it when writing my own answer (because it was edited out).
In the example above, should the question that has been edited out be edited back in to prevent confusion to future readers?
In general case, what is the recommended procedure?
