User Story : Following a person

In trying to implement SWAT0 there seemed to be a dependency on following a
person.  I found that's a user story on it's own so I think it's a good
starting point for implementation:

https://www.w3.org/wiki/Socialwg/Social_API/User_stories#Following_a_person


I have a couple of questions on the first description of part 2 in :

https://github.com/w3c-social/activitypump/blob/master/userstories/following-a-person.md


1. Is this currently implemented anywhere that can be tested, or at the
moment a design?


2. Re:

He ends up at the following URL, her internal *profile*:

https://acmegamecorp.example/people/beth_m_bost/

And:

  "object": {
    "@type": "Person",
    "@id": "https://acmegamecorp.example/people/beth_m_bost/"
  },


Should that then say @type Profile?  The profile being an HTTP page that
contains information about Beth.  This would be more in line with the way
we implement things in SoLiD.
