But being Google it might also be just general lack of care.
I need to confirm this, but it looks like they're adding a 5-second delay to the server response time if the User-Agent is a browser they don't like. (Changed the user-agent to Firefox and the delay immediately went away.)
I have known about that for about as long as I've had this problem and I think it used to work back then but today I consider it a purely decorative element.
