Or someone has tried to explain it to you and failed. Whatever the case may be, your problem is solved by the Oprah-style explanation of RSS.
RSS is a way to get a quick list of the latest story headlines from all your favorite websites and blogs. RSS makes it a lot easier and faster for you to get the storeis you care about from around the web.
I use NetVibes for my RSS feeds because it allows me to organize my feeds into topical groups and to see which stories I haven’t read yet.
