I'll be honest, I complained about my total lack of ability to find anything in the documentation and they emailed me back to ask for suggestions on what to fix. I never got back to them. I really should find time.
It was funny because in my frustration, I left a comment on the last page I looked at and they responded with the completely reasonable question, "Why were you looking at that page? It doesn't contain any of the information you were looking for." It was such a great summation of what my problems was that I felt difficulty in finding an appropriate response :-). Possibly this is too unfair, but I felt like the question, "How should I have found the information I was looking for?" was something that had never occurred to them. It's pretty applicable to virtually everything I've used from Google. It has that feel of, "If you don't already know, then you don't deserve to know".
