Erick Tseng, Google's Senior Android Project Manager, tweets about his departure for Facebook.
Despite the numerous avenues he could have chosen, Tseng took to Twitter to break the news:
About to begin a new, exciting chapter in my life. Heading to #Facebook on Monday to help innovate at the intersect of mobile and social.
TechCrunch thinks he's shifting gears to work on the Facebook Android App, which feels a little bit insignificant to me. However, he'd be the right person for the job.
Google said in a comment, "Erick made many great contributions here, and we know he'll do the same in his next endeavors. we wish him all the best."
