Path

With obile photo sharing becoming more popular and Path’s focus on being a personal network, and setting a limit to the number of connections you can add, will attract users looking to connect with their real-life connections. Also, focusing on mobile is smart, considering more users are now checking social networking sites on their mobile phone than e-mail. The founding team also has some star power with the likes of former Facebook senior platform manager Dave Morin, Macster co-creator Dustin Mierau and Napster co-founder Shawn Fanning.
