I believe they are the same. The clue is that when you go to "My Home", there is an option for looking at your "Buddy/ignore List" and when you view it, it shows your list of people who are shown as your "Friends" in the Profile view. It is sort of confusing, isn't it? I think we ought to get rid of the word Buddy and replace it with "Enemy" and then we could have a friends list and an enemy list.
Cheers,
