People discuss the quality of questions a lot here and on SO. I see less thought put into how to write really great answers. Unfortunately, too many answers seem to be worried about how to write a really fast answer. 

1. Does SO need a "How to write great answers" page?
2. What are the qualities that make a really great answer?
3. What things are most unhelpful in an answer?
4. Should a page like this discuss the things that will get you into trouble with the moderators?
5. Are there other pages on the web about answering technical questions like "How to Write Questions the Smart Way" already explains how to ask?
6. If we had such a page would anyone read it?
