I have created a pinterest board of what I think is popular with you as a result of observations and interactions with people from ages 12-18. To have a look at what is popular go to http://www.pinterest.com/ndaunt/boards/
I have been also been reading a few different articles on what is popular amongst the youth and one thing I have noticed is the trend towards young people using forms of social media other than Facebook. Is Facebook losing its popularity?
