Jeeves has disappeared from his home of the last 4 years, the http://www.ask.co.uk/ search engine.

A link to the explanation tells visitors that 21 September will have an update along with possibly some new personalization features to the search engine.

As a part of the story, you can now choose a guest butler to replace Jeeves, including Russell Crowe, Marilyn Monroe and Elvis.
There's also a competition for an Apple iPod if you forward on the guest butler page to a friend.
