Google has launched the new iGoogle gadget known as "What's Popular".This gadget displays the most popular content from the web.This gadget bears a resemblance to Digg, Reddit or Yahoo Buzz,as one is able to vote the web pages. In other words ,it is possible to rate items that you like or dislike by just clicking the ratings buttons displayed close to each item. Later if you change your mind, then the ratings can be changed anytime. The What's Popular gadget ultimately searches what users liked or disliked in order to improve its ranking of interesting items.Also ,it is possible to add content that the users find interesting.

What's Popular utilizes algorithms in order to search interesting content from a combination of submissions and trends in aggregated user activity from Google services such as YouTube and Google Reader.Three categories such as stories, images and videos are available and usually all the pages are sorted according to the algorithm.
