The former senior platform manager of Facebook, Dave Morin launched a new social cum personal networking startup company, Path that limits the number of friends at fifty. Path is more appropriately called The personal network because it goes against the concept of Twitter or Facebook that allows to make any number of digital friendship. Dave limits the number of friendship at magic number 50 because, as per Oxford professor of evolutionary psychology Robin Dunbar, 15o is the maximum number of friendship a human brain can handle. The company said; "Because your personal network is limited to your 50 closest friends and family, you can always trust that you can post any moment, no matter how personal”.
