How did you learn it? I use it occasionally to debug memory dumps after an application crash but I know that WinDbg can do so much more than show me the stack just as the application crashed.
I learned it at Microsoft. When debugging issues in Windows, it was pretty common to leave a remote server open and pass it around among colleagues to find the right person who knows what code is failing. You could see what the remote party was typing and doing. It was a pretty social way to learn your way around.
