[IxDA Discuss] 2 part button - industry standard?

[Brett Ingram]

Hi all,

Check out the "Add To Wish List" button at Amazon.com. It consists of  
2 parts that can be clicked on. Does anyone if this has become some  
kind of "industry standard"? Also, any ideas where this kind of  
button first originated?

It doesn't seem very common to me. It doesn't seem particularly  
usable either, since it isn't that clear that there are 2 parts of  
the button that can be clicked.

To see the button you just need to go to any product page on Amazon  
and it should be on the right side.

Thanks
Brett
