LiveJournal's friends group model doesn't store, however, that a
particular group means "Colleague" or "coworker" or "family".

These groups are just plain text strings: there is no semantic meaning
that can be derived from them.

Additionally, the presence of a user existing within a group (or even
the existence of a group) is private -- no one other than the owner of
the group has the ability to find out what groups a particular user has
created, or who is in them.

Exposing this type of information would be a significant violation of
the trust of LiveJournal users, since the policy has always been to keep
that information as private as possible.

So: Yes, LiveJournal allows for grouping of contacts, but those
groupings are not public information, nor are they semantically

(I don't work for LiveJournal either, but I did write a fair chunk of
the original FOAF code, so I'm aware of a bit about the backend.)
