In this second segment of our two-part interview, Aydin talks about the trends he believes are worth following and the sectors he sees as over-hyped or over-crowded.

A few areas he sees as promising are healthcare, online education, and personal genomics. An area he things may be crowded is applications for both iPhones and social networks. "Gaming [apps] on top of social networks have been successful, but not many others," he said.
