RockYou is among the top two most popular application development groups. They have applications including XMe, Likeness, Vampires, Zombies, Werewolves and others. I had the opportunity to interview Jia Shen, the CTO and co-founder of RockYou back in August. Jia was present at both the Community Next event as well as the Graphing Social Patterns event, both of which I attended last week. Below is a video of him speaking at Community Next about the business of Facebook applications.
