The issue to me is that if each website developer develops their 
own haptic vocabulary (checkbox expressed as this sensation, 
link as that sensation), site visitors would need to learn a new 
haptic "dialect" for each website (much as they do now visually 
for sites that mess with default link appearance).

Ideally, the browser manufacturers would agree on a default 
haptic behavior, and sites would only override those if there 
was a specific good reason.  On the other hand, a haptics-using 
site visitor might want to override certain haptic properties 
in their personal style sheet.

Hope this helps,
