To approach the functionality of Google+ circles, I'd like to move all friends from one Facebook list to another. For example, I'd like to move most of the people from my list for where I work (smart list) to Acquaintances, where I can set that list to have less access to my profile.
How can I select a sub-set of friends from one list and move them to another in Facebook?
edit http://www.friendmanager.org/ looks interesting, but it only takes 3 lists (general, close friends, acquaintances). I can't find a way to move more than one friend at a time (not fun when you have 400+).
