Add to My Like feature helps you in adding a member to your likes list. You can add profiles to your 'Like' list by clicking on Add to my 'Like' (♥) button on a member's profile.

This enables you to create multiple groups based on hobbies, passions and your likes to categorize your interests. So you can never mix-up your "yoga-meditation" friends group with the "party-loving" buddies. 

You can also edit the list names as per your convenience and maintain 5 lists. This list can be edited from the left frame by clicking on 'I Like' column. Also, members in this list can see your photos irrespective of your photos privacy option selection.
