Hm, interesting. Your comments about full screenshots with callouts are
well-taken. I like to think that I use those kinds, but it never hurts to
have a reminder of what really helps.

It seems we may differ on a more fundamental level: to user-monkey or not
user-monkey? :-) As you said, there is room for both approaches. I
certainly agree with that. You write that you prefer teaching users to be
self-directed. But for the situation I'm in at my company, I think of my
goal as supporting users who forget, or wonder, how to do something, or
what some function call is, or what some term means, or users who wonder
whether they *can* do something in our environment.

More generally, I guess my goal is to support the people who don't want, or
have, the time to become an expert in our product. And I think that even
experts will forget how to do things from time to time (they may just know *
what* *to look for* more quickly than a novice.)

I've never expressed it like that, and I"m not sure how I arrived at that
philosophy, but those words feel accurate to me. Thanks for helping me
formulate it :-)

To everyone else who is submitting research: keep it coming ...
