A Grid is an infinite matrix of people.
Users connect their social profiles and the Grid will analyze activities and co-relate them with people who have similar activities.
Everyone in adjacent grid are people with similar activities on social networks and you can choose and ping them for a date or whatever. You cannot ping a person outside 8 x 8 of your grid. But you can ask recommendation or suggestions to reach that grid by sending an interest.
From inside Its an engine to compare two people activities across different social networks to figure out how common they are.
It may give suggestions to improve your social skills to reach a particular grid.
(Just an idea.)
