'Usability' is an HCI term. See: http://en.wikipedia.org/wiki/Usability
In this context user confusion (and clutter) would tend to count
against usability. Obviously other factors apply. And whether a
particular feature makes a significant impact on the usability of a
site is a different matter to whether it is itself usable.
