Garry Tan of YCombinator shared a post showing the survey data of little over thousand teenagers. He asked them to pick social networks that they used more than several hours per week. On his top 5 chart, there were Tumblr, Facebook and Twitter. But there were also Instagram and Snapchat. They showed up 21% and 19% of the answers respectively.
