LeapTag runs in your browser tool bar. As you travel the Internet you simply tag pages to associate web content with your interests. We call this dynamic tagging and it enables LeapTag to create a contextual definition of your interests. When LeapTag returns your results, you further refine your definition by voting positively or negatively on the items you see.

Because the current personalized news sites don’t understand location information about their readers, they are unable to recommend news that is related to the local environment of the readers.

Just my thought: I always wanted to implement our main site as an self learning, intelligent tool, presenting a homepage of personalized content. Not by profile, but delivered by your browsing interest in the site itself.
