I discovered RSS Feeds through Firefox. When I tried and got addicted to Thunderbird I checked that it supports them as well. All it does is automatically update stories and news from a web site. For example, I have subscribed to feeds from CNN, The Sims 2, Discovery News Animals, Kapersky Antivirus and many more. Instead of having to open my browser go to each site and see if there is anything I'm interested in, I open Thunderbird. It updates the topics while I'm reading my email. I browse through the headlines and if there is something that catches my attention, depending on my settings for that feed, the page will download in my preview pane or open my default browser and go directly to that article. On some sites the feeds aren't easy to find. Often I have to do a site search which is faster. Some sites have the orange rss icon right on their home page. Firefox uses live bookmarks for rss feeds and opera will add a feeds menu the first time you subscribe to a feed through it. I have to say I recommend trying Thunderbird as it has way better controls. I don't know if Internet Explorer or Outlook Express supports rss because I don't use them.Sorry I didn't reply sooner, but I've been a bit busy with my new kitten. Hope this helps.
