URL did not work but RSS feed on Altered Plates did.

I managed to add Altered Plates to my blogline via the RSS feed on the website. But adding the URL into the ADD tab on blogline did not work. Odd. I was unable to add an RSS feed on my blog. I went to gadgets and it said to add RSS or Atom click here, but no RSS symbol. If I click on Atom at the bottom of my blog it shows me what I have recently added. If blogline is like managing your bloglist then why am I not seeing a RSS feed on my blog? Any comments? All welcome.
