Do we need another from Google?

I am shocked to hear that Google is working on another search engine, Caffeine.

Developers are inviting users to use the new service hosted at
http://www2.sandbox.google.com/

And I guess most of the people would be eager to provide feedback. And that is what that keeps Google on top.
User feedback is a priceless treasure and Google is able to get it on a large scale.

Sometimes, I feel that we ourselves are making Google intelligent.

Anyways, at the end of the day, a user wants fast and relevant results.

Will people get addicted to the new Google Caffeine.
Well, I am already addicted to the natural Caffeine. ;)
