I really wish someone would re-write all of AWS documentation and make everything simpler to understand. I'd like to use AWS but the documentation as-is would take hours to read.

I'm sure they expect you to use a client written in your language of choice, not actually send queries to the API manually.
For the most part they are created via code generation (to my knowledge), which while not necessarily making for the best user-friendly API (Although it's not bad), does make it fairly consistent in terms of groking how to accomplish automating a task.
