Rubrics for user experience design

Alex Wright on Calvino's heuristics:

Calvino's Six Memos for the Next Millenium are:

Lightness
Quickness
Exactitude
Visibility
Multiplicity
Consistency

I doubt that Nielsen, Norman, and a thousand monkeys with typewriters and HCI degrees would ever improve on that.

So interesting I wish he'd explained more about what each entails - especially since ambiguity (one of my favourites) is missing.
