Finally! As for the 'find friends' and connection to Facebook, it's just integrated to search people's FB friend list, and automatically populate those that are on Spotify into the friend list there. You can build your own friend list - find users, and "follow" them.
Found Tim through Joe's list. For some reason, I get "user profile failed to load" trying to find you each individually. Maybe because you're both cheap bastards on the free version?
Follow me please - you know who I am. if you search "spotify:user: <username>" in the search field, that's how you find people.
BTW, RJ doesn't use it too often.
