Don Park has a draft of a user interface to diagram the level of closeness of one’s friends. I hope this is intended as satire!
A Friendship Circle is basically a nested rings of people (represented by icons with miniture photo and name) around a person. To use the Friendship Circle, the user drag and drops icons from a palette of friends to the circle. Note that this can be done using DHTML+CSS.
Does one spend time with this graph every morning, and move one friend-counter closer, after he has been helpful in a difficult situation, and move one of the mistress-counters further away because she used a unappealing perfume?
Very clever and amusing if satire. Repellent if sincere. It might have a certain appeal among playboy geeks and junior high-school girls.
