Hey David,
The Helper that you look at is creating a link to Jomsocial. That is correct, but we use this only to link the name of the user who created the link to jomsocial. In the current version the readmore cannot be linked to the jomsocial profile. However there are good news! I've already implemented the following for CB:
-when the user registers on the site we automatically add an entry with this user's location on the map. When the user updates his address, we automatically update the address.
I'm going to implement the same thing today and you'll be able to have the readmore button point to Jomsocial.
Regards,
Daniel
