Several times I've received multiple answer to a question I asked, with each question having good information but only a portion of the answer. For example, in this recent question:
Which tournament format best emphasizes winning (as opposed to avoiding last place)?
After reading the three answers and various questions/comments to the answers, I now have a good answer. But it wasn't any one answer or comment that provided the answer. It was all of them collectively.
Here are other examples I've run across (the last Q is not mine):
What is optimal end play in Settlers?
What is a good resource to discover new games?
So how to handle this? Do I need to improve the question? Is it best to work with the better of the 3 answers and see if I can get that person to incorporate information from the other 2 answers and various comments? Or is it better practice to try to write a completely new answer that tries to pull together all the other answers and comments into a more complete and coherent whole?
NOTE: I suggested in response to the blog idea that content with multiple answers could be reworked into a blog post. The above 3 Q&As cited are examples where rewriting into a blog post would likely be better than the original Q&A - especially if it were done by someone with specific expertise.
