Google Analytics is great for seeing the number of page views, but it won’t give you information about specific users.
We just released an alpha version of Heavy Analytics (http://heavyanalytics.com) for single-user WordPress installations. This plugin handles analytics and reporting on the WordPress and user level, picking up where Google Analytics leaves off.
In the near future, we will be releasing a BuddyPress add-on for Heavy Analytics, which will give you all sorts of information about how users are using your BuddyPress site – how they are interacting with each other, who are the quality contributors, etc.
