-====== Flock ======
-A flock is a list of [[Flockr]]s as generated by means of [[Proximities|a proximity function]].
-The list changes dynamically as the input to the proximity function changes (e.g. because of buddies joining, leaving, updating their profile, being added or deleted).
-In other words, while the proximity function can be regarded as an "intensional" representation of a group of friends, the flock is the "extensional" representation of that group. For example, if ''f'' is a flock of "all of my friends who are older than 25" (an intensional description), and the friend list is "[Alice (26), Bob (22), Carol (24)]", then the flock contains only Alice (an extensional representation of the group)
-=== Implementation ===
-Conceptually, a flock is a list of flockrs. Technically, a flock is implemented as a list of profiles. From the profiles, the flock can acquire the flockr's unique username. Given the username, the flock can acquire a far ref to the flockr via its own "owner" flockr.
