Congoo, a free information network, has launched News Circles, a platform where users can select from hundreds of news categories to build and share custom news portals. The service includes tools for blogging and sharing thoughts with a specific group of users in a public or private forum--at no charge. News Circles lets each user decide precisely what news subjects are important. Congoo uses proprietary clustering technology to group related news articles from various sources into story groups. News Circles will also allow users to monitor over 100,000 daily news stories for articles containing their own list of keywords.
