+### Why isn't official documentation more helpful than Stack Overflow?
+
+Often official documentation is more geared toward being a concise reference.
+Stack Overflow is more of an example-based learning environment.
+
+Sometimes you need to know the specific details. In those cases, you can dig
+into the spec, with all it's lawyerly language, and try to decipher what it is
+you have to do.
+
+Other times, you just need a getting-started example, and Stack Overflow is
+great for that.
+
+Both types of documentation have their purpose.

+your're trying to do will get you 99% of the way there in an interview.)
