RSS is a technology that has not had the marketing push behind it that it deserves. For anyone interested in news, it is a very simple and effort-saving way of picking up the headlines and allowing you to review just the one(s) you want - and lots more info can be found at the Google Reader FAQ Page. On the other side, newspapers and broadcasters are generally very good at putting RSS feeds on their websites. Black mark of the bunch goes to the corporate press officers, though.
Woefully few companies issuing corporate press releases have RSS feeds - some people know I have a passing interest in helicopters, and I'd expect the major manufacturers to have RSS feeds on their websites. Shock Horror - NONE of them do - check out the websites of AgustaWestland, Bell, Eurocopter, MD Helicopters, Robinson and Sikorsky. I grant you that the parent companies of Bell (Textron) and Eurocopter (EADS) do have RSS feeds, but the helicopter manufacturers do not. Hang your heads in shame! Always look out for the RSS feed icon - the orange square with the white "radio waves" broadcasting from the "transmitter". They're usually seen on any blog - for example, check out the "Subscribe to Posts (Atom)" link at the bottom of this page.
