I recently answered this meta question about falling number of accepted answer with my opinion that its not necessarily a bad thing that there is no single canonical answer to all questions on this site.
On some StackExchange sites, such as StackOverflow, there is often one canonical correct answer. On some sites (I'd argue this being a good example) there may be multiple, non-conflicting acceptable answers
This would be improved by adding information for typical jet aircraft (see other answer)
I questioned whether this was a good idea, and he responded
One of the goals of the site is to revise answers to make them better, so that ultimately we have that "one perfect answer" the the question. It's the wiki part of the site, and the way that it is now, neither answer completely answers the question. For what it's worth, I would not have added a second answer (since it is not a complete answer) but would have edited yours
So, by way of continual improvment of this great community, what are some opinions? Should we take the StackOverflow line that "Opinion is bad" and therefore should strive for one canonical good answer - or, like me do you prefer that this community is full of opinion and experience and therefore multiple answers are a good thing.
I should clarify one point - I may not be using the best examples above - they are simply what made me think of this. In the case of the answer ive linked it could be that I should have updated my answer to have the full information, rather than leave a question which clearly has a canonical answer in two parts. Some part of me likes that I shared the rep with another user.
