Leave it to a former Facebook employee to create the anti-Facebook. Dave Morin, who used to work as a Facebook platform manager and at Apple (NASDAQ:AAPL) before that, combined his design and social-networking skills to found Path. It is a mobile-only social networking site designed for your inner circle.  In a nod to Dunbar’s number, which proved humans only have the cognitive ability to maintain stable relationships with 150 other people, Path limits the number of friends you can share with to 150.
 
Unlike Facebook, Path is designed exclusively for mobile useage. Its intuitive interface is meant to foster strong, intimate relationships and a high level of self-disclosure. As Facebook grows more complicated with every update, Morin may be positioned to catch a backlash of users seeking a safe haven to share personal information. In terms of monetization, it also doesn’t hurt that advertisers put a higher premium on trusted, proven social media connections.
