save eleven hours every second! Oh... that's a collective eleven hours? I knew there had to be a catch.
Seriously, when I ran a Google search earlier today and saw the results change in real time when I typed, I had a, "What the... Oh, another Google experiment with Ajax" moment. I expect I'll find it useful over time. And I expect Google will encounter resistance from those who liked things the old way and will interpret anything Google says as, "It's not a bug - it's a feature".
I suspect this explains why I now sometimes get a warning when trying to close a Google SERP.
