A lot of websites still use Java on the server-side, but not necessarily piped down to your browser. A security flaw like this really impacts corporations more than most regular web surfers realize if it needs to be disabled/removed. Mobile devices use Java, maybe your big screen TV even.

You may find that certain features of your favorite website may not work for a while until a patch is distributed or they come up with a workaround.
