This module integrates with Google+, the recently launched social network built on the concept of social circles. There is no public API for Google+ yet, but you can sign up to be notified as it is released. Without an API, we are limited in what we can do, so the module currently just provides the following points of integration:
- Google+ profile reference field: provides a simple profile reference field with a custom textfield widget that stores the numeric value of a Google+ profile ID as found in the profile URL. The default display formatter displays a link to the referenced profile with options to use a translatable or customize link title and set the target window. This can easily be added to the user fields to link Drupal user profile pages to their related Google+ profile pages.
I'm up for ideas on how to develop this further, so don't be shy about posting ideas in the issue queue. I also look forward to having a full API to play with. : )
