comment Why do we say that door knobs afford twisting?
Now that I think about it, I want to draw a distinction between having good affordances and having good ergonomics. Having a good affordance means it appears possible to physically interact with an object the way it’s meant to. Doesn’t mean it’s easy or even it’s necessarily the first thing you try. Having good ergonomics means it’s easy to physically interact the way it’s meant to. Whether it appears physically possible or not is a different matter. A door knob and handle have the same affordance, but the door handle has better ergonomics.

Don't confuse with ergonomic.

comment Is there a common practice for cases of very delayed responses?
Ideally, you'd communicate the approximate time to run the process before the users even start it --that may impact whether they want to start it at that moment or not. If that's not technically feasible, the next best thing is to provide an approximation immediately or shortly after it starts. A progress bar can do that, although a reasonably accurate "time remaining" countdown is better. Badging and notifications can indicate when the user can return to the window when it's fully occluded. I don't know how or if they can be used for a web app in a browser.

comment View vs Modify “mode”
@Tohster: Good point on the mouse. Even if the user were using the keyboard for data modification (e.g., a text box), s/he probably needs to switch to the mouse anyway to carry out the viewing task even if there weren't a mode (e.g., to use scroll bar). And, yes, all these numbers are pretty rough approximations, so the framework only helps if the costs grossly outweigh the benefits, or vice versa.
