Instead of having to repeatedly visit websites to check for updated information, Web Slices allow people using Internet Explorer 8 (download link) with Live Search to keep track of information from within a webpage right from the Favorites Bar. When a website has a Web Slice, users will be notified a Web Slice exists within that page in several ways. A green Web Slice icon will appear in the Internet Explorer Toolbar (where the RSS feed icon usually is) notifying you that the webpage you are on has a Web Slice. As you move your mouse through the webpage, when you mouse over an area of the webpage that has the Web Slice, the Web Slice icon will also appear.
Live Search provides several really neat Web Slices:
- Live Search Weather Web Slice: Provides the current weather for a city or town and the forecast for the next 4 days.
- Live Search Traffic Web Slice provides latest traffic for a given city in your results.
- Live Search Top Stories Web Slice: Stay on top of the top stores from Live Search!
- Live Search Finance Web Slice lets you search for stock results on a specific company on Live Search.
