- We can find in Stack Overflow not only an FAQ written by one team (who might not necessarily know all the questions from the field), but actual question written by anyone corresponding to an actual need encountered on the field.
Each time there's a question and an answer logged there, it has high chances to help again any other person who would encounter it.
- There are several mechanisms to easily identifiy relevant content, such as the search bar (of course) and the tags to see all questions related to a topic.
- Additionnally, it's easy to refer to a question and its answer by just sending a hyperlink to a colleague who needs it.
