Even though facebook graph search is an interesting feature recently added in facebook, for some people , the first impression has been ‘creepy’
In graph search you can search terms like
‘Movies that movie actors like’
‘People going to watch today’s soccer match’
‘People who like wine ‘
and this would refer to someone totally unrelated to you except that in your search query .
Graph search promises to show only the contents that are publicly accessible to you. That implies same search will produce different results for different people.
Due to this feature , people totally unconcerned with you can find you in results . This can make it necessary to make everything private on your timeline , a fear of ‘being shown on other people’s ‘ search results.
So, if you are wanting your Facebook to be a private place for you , where no one you don’t know bothers you , you’d better make every of your post and interests private in privacy settings of your account.
