[uf-discuss] Hidden metadata no microformats

I can imagine Web designers wanting to associate invisible metadata  
with a button (that says "Add to Calendar" or "Map"), so that a  
microformat aware Web browser would detect the metadata and register  
down clicks on the button as acting on the metadata.  This  
information would likely appear elsewhere on the page (probably also  
using microformats), but the button provides a visual affordance for  
the action.

In our current designs, we are considering changing the mouse cursor  
when the user hovers over microformatted content, but that doesn't  
present the user with any indication that they can act on the data  
until after they have moved the mouse over it.

So in this particular case, I think leveraging invisible metadata  
makes the interface more usable overall.
