how to track user profile page views? I want to track page views to a user's profile page similar to what the core "statistics" module does for node page views.

I don't want to use profile2 for my site, otherwise I could probably use the statistics module.

Eventually I want to use the Google Analytics module to track page views to cached pages as well.

I'm looking for a simple solution/workaround that I can use right now.
Have you checked the User Visits Advanced, and the User Visits modules?

The User Visits Advanced module is a module that depends from the User Visits module. It is extremely useful for social networking sites that wish to provide their users with statistics about the number of time a user's profile page is being viewed, and by which users.
