The U.S. service, in conjunction with MSNBC, constantly tracks more than 4,800 news sources around the world, and aggregates the top stories into a categorized home page. In both design and sources of information, NewsBot is similar to Google news and other online news aggregators.
What sets NewsBot apart are the history and personalization features designed to help you easily find news relevant to your own interests. As you read stories, the site tracks the topics that you're interested in, suggesting similar stories in related areas.
The site captures no personal data other than the stories you've read. Recommendations for similar stories are made based on stories that other NewsBot users have read. "A great comparison is much like what Amazon does today," said Justin Osmer, product manager for MSN Search, citing Amazon's "Customers who bought this book also bought" feature.
