Dave Morin is probably best known for his impact on social networking, first as an early Facebook employee working on initiatives like Facebook Connect and more recently as the founder of Path, a startup that strives to be a more intimate social network. But before he worked in either of these companies, Morin managed higher education marketing at Apple. Path recently sold to Daum Kakao, the company behind the popular Kakao Talk messaging app, for an undisclosed amount.
