[development] profiles as nodes

[Khalid B]

The "users as nodes" and "comments as nodes" were discussed in  the
relationship session.

Not the details of whether it is a good idea or not (there seems to be
disagreement on this in the community), nor how to do it, but rather
along the lines of "if we had this we could do much more with relationships".

Perhaps profiles as nodes is a step in that direction ...
