From Diodia Software:
The RSS Feeds Toolbar monitors RSS feeds and displays the latest headlines from the feeds in an Internet Explorer toolbar. The headlines are updated at a configurable time interval. A button in the toolbar launches the full article associated with a headline. The toolbar is not a full-featured RSS reader. It just makes it easier to stay up to date. For example, instead of navigating to the home pages of 10 news sources 10 times a day, you can just add the corresponding RSS feeds to the toolbar and get all the latest news inside the Internet Explorer. The toolbar works well with RSS feeds that are continuously updated and include publication date and time for each news item. Not all RSS feeds fall into this category.
