“The maximum number of individuals in a society or group that someone can have real social relationships with is 150” – Malcolm Gladwell, The Tipping Point.

So how do you keep in contact with people that aren’t your close friends efficiently and conveniently?

Introducing friendly.

Friendly is more convenient and targets the problem of loosing relationships and connections more directly compared to existing methodologies because it provides users with the freedom of using a list of contacts in the ways they see fit, in times they see fit. It can be as personal and as professional as the user wants it to be.
