On the profiles list page, as a user, I would like to be able to quickly see if any profiles have recently been updated. As an example, a new user joins up and doesn't add to their profile while exploring. Other users nearby notice this profile and see that it is empty. They then might ignore the profile, even later when the user has decided to add new images or lengthen their profile text. Apps such as Recon will add a tag to profiles for a few days after the user has uploaded new images.
