What is the difference between Public and Personal POI Groups?
When a POI Group is created, the user has an option to determine the level of access other users will have to the group. For a ‘Public’ group, all users can view it. At the ‘Personal’ level, only you and the specific friends you choose will be able to view it. In effect, a ‘Personal’ POI Group is private (only viewable by you) until you share it with other friends.
