Incase any of you have installed this or are thinking of installing it, DON'T. It's broken and may damage your user account when you're logged into the site.

What happens is it "pre-fetches" links without you actually clicking on them - all very well but what happens when it pre-fetches the link that logs you out of the site, or changes something else in the user area?

It may also be responsible for someone's experience of being logged in as somebody else, caching personal information on google's servers and serving it up to other people under the mistaken impression it's just a static page.
