> Definitely great to see the box unchecked as default.

I'm not so sure if it's a default setting. I guess it inherits some other settings that Google used to have earlier. I have always allowed Google to use info from me, as they pleased. So, when I visted the link, it was checked for me.

Mind was unchecked as well. A little confusing seeing the headline and then it looking like I had already opted-out somehow. Made me wonder if it was one of those double-negative check boxes for toolbar installations.
