RSS Feeds

A few weeks ago while I was reading about RSS Feeds, it sounded like a great idea. I signed up for an account and started to peruse the feeds available. Although it was fascinating, I got really bogged down just looking at possibilities. I finally decided on something. I watched the tutorial on how to add a feed. I felt fairly confident I could do it but failed miserably. I couldn't figure it and haven't gotten back to it to try it again.
