The first thing users will notice is a very attractive new home page, with pretty buttons to narrow a search into a silo, such as images, maps, or blogs. Users can select one of several photos as a background image on the main search interface. (In the future, you'll be able to use your own image). When you begin to type in a query, a drop-down box gives you suggestions to fill it out.
The new interface splits up search result pages (SERPs, in the lingo) into three panes. In the middle, you get your ads (by Google) and your main links. If there's an editorially-created "smart answer," as there is for a popular query like "Speed Racer," you'll get a useful little blurb above everything else. Ask.com's editorial team, like Mahalo's, creates content for the most popular results (Mahalo also curates search results, which is a useful additional service).
