As the name implies, what this plugin does is scan your facebook and gives you some important statistics information about your facebook account in relation to your activities and your friends activities in your account and timeline.
It will show you a list of your friends who have the most comments on your pictures, and your statuses and liked your pictures or liked your statuses etc.
All this data will be collected and shown to you in a tabular form for you to see which of your friends are really into visiting your profile and also engaging with your profile. You will also be able to see how many comments and status updates you've actually posted on your own facebook account timeline.
We know sometimes you might feel the need to see which of your friends actually want to communicate with you on your facebook by leaving you comments and liking your facebook posts and pictures in a way to show you they are watching you and interested in what you have to say on facebook and pictures you decide to post on your account.
