They need this in the FAQ
Someone is your Friend if you add them via your Friends Activity tab. I think this tab might not appear until someone else adds you, which is a bit gay.

Someone becomes your Fan if they add you. You will see them on your Friends/Fans list and will be able to add them as Friends.

Hope that makes sense.

On your Friends Activity page, you'll see all of your Friends' root-page posts, and posts they clicked I Like This, in /board, /talk and QOTW.

I've added you all* so hopefully your Friends Activity link should appear at the top of the page if your blatant plea for attention hasn't already made it happen :-P

* I reserve the right to remove you if your posts are shit :)

Edit: Friendship/Fandom doesn't occur on clicking I Like This.

Edit edit: there is some basic Add Friend functionality on /board, there might be on /talk too. Dunno why they don't incorporate it here too.
