News comes way that Ask has announced two new very useful features named Zoom and Web Answers. John Batelle has a quick & easy write up on those features but I will try to make it even quicker for you below. Chris Sherman & Gary Price has a more detailed write up at SEW.
Zoom: Search Ask for the beatles and look at the right side of the page. "Narrow Your Search", "Expand Your Search" and "Related Names" make up the zoom feature.
