LiveSearch Turned Off
Yahoo!-owned AlltheWeb had their LiveSearch experiment running for over a year, display suggested search terms as you typed. Now, the LiveSearch address just redirects to Yahoo! I assume that this is because of Yahoo!'s new search assist feature giving a similar experience.
Karen posted about this on Dec. 13, and it is still re-directing, so it seems likely that it is gone for good. AlltheWeb itself continues to work, but remember it is just using some portion of the Yahoo! database.
