www.24eyes.com

With www.24eyes.com you can present RSS newsfeeds in however many windows (called "widgets") you care to arrange on the page. You can define the newsfeeds by selecting from dropdowns, by specifying an rss-feed url, or by searching for rss feeds by topic or provider (e.g. "state department"). You can also create a feed search; for example, by searching for"public diplomacy" in Google News, you've created an RSS feed for occurrences of those search terms that you can channel into one of your www.24eys.com windows. Finally, you're supposed to be able to publish your page and/or make it available to others, but I couldn't get either of those features to work (I've sent them a message about it...)
