Twitter

Many people at a young age use twitter to comunicate with eachother like telling friends im going to be hanging out and who wants to come. But you can use twitter for educatiob too.

The problems that could possibly happen is if say a teacher or student says or tweets something inapropriate when not in the school hours and the teachers and students would know about it and teenagers do use say "inapropriate" content to their tweets so it could very much happen.
