Favourites module will let your site users add other site members to their list of favourites. The action does not require confirmation from the part of the 'favourited' person. They can, however, see the list of people who added them into their list of favourites. It lets people show their interest in a subtle way.
Besides, once you've added someone into your list of favourites, you can follow his/her public actions in the Activity wall.
