Cortana in Windows Phone 8.1 is garnering plenty of praise for for its ease of use, personality, and features , but now it's time for some of that personalization magic to make its way to Bing.com with the addition of interests. After being booted off the search key on Windows Phone devices by Cortana, Bing is getting personalized updates that tap into the power of the web. And it's a simple as clicking a star to register your interest.

Once you're signed into your Microsoft account on Bing, all you need to do is click on the star next to a search result to get updates on it as they occur — Bing will do the watching for you. Interests available to start out include travel with trip planning and flight info, local traffic, and weather. There's also a Daily Glance option to roll all of that together into one view. Microsoft says that they'll be rolling out new interests for Bing over time.

When on Bing.com your interests will appear at the bottom of the landing page, updated with whatever the most recent and relevant information might be. These interests can also sync with relevant Bing apps and directly with the Windows Phone operating system, and you can individually toggle notifications for the web, apps, and Windows Phone.

With the power of Bing at hand, there's a lot that could be done in the future with interests. What interests would you like to see Bing give you the option to track?
