"Dr. Sameer Hinduja educated Williston students on Tuesday (and a gathering of parents the evening before) about the clear and present dangers of teenage use of social media. An expert in his field, Dr. Hinduja’s deceptively youthful appearancegained him quick credibility with our students—a hip college professor connects well with those in middle and upper school. One aspect of his message was not especially new: Electronic postings last a lifetime even if “taken down” from original sites. Yet the advice he gave students was newly framed for them. Dr. Hinduja also focused as well on the world of cyberbullying, interspersing his lecture with YouTube videos made by teens who have suffered from the humiliating effects of campaigns waged against them."
