Yahoo’s new cross-lingual (not multi-lingual) video search is wicked cool, but they have this weird use of a checkbox. There are 2 radio buttons and one checkbox. If you click the checkbox, the two radio buttons grey out. The only explanation I can think of is that it’s a hack in the code – somehow it was easier to implement this than to just have the checkbox as a third radiobutton (which would be the correct way). Strange though, to see such a beta UI hack on Yahoo.
