Apps, sites, and social tools are working to prevent teen depression, suicide, and cyberbullying, and one campaign is riffing on popular videos to show that unkind words are not anything to laugh at. Jimmy Kimmel’s famous “Mean Tweets” series usually features celebrities (and one President) reading insulting tweets about themselves aloud. Nonprofit Canadian Safe School Network emulated the videos' style for their anti-cyberbullying campaign “Kids Read Mean Tweets,” replacing celebrities with teens and making the canned laughter die out as they read. The video has garnered over 2 million views on YouTube in the last week, spreading the message that “Cyberbullying is no joke.” (BuzzFeed)
