It's called "Cyberbaiting", and it is when a student baits a teacher into a heated argument and capturing it with a mobile device for upload onto YouTube and social networking sites. Anytime a student is acting out there is a slight possibility that he or she is baiting you so another student can record it. It's a very, very slight chance but its real. More likely is the possibility that your reaction--especially if it's a habitual explosion or rant--can be recorded by another observant student. Almost all phones, tablets and devices have the capacity to record video, including HD and then immediately uploading it. A vid could be posted within moments of the event. Unfortunately video is also easy to edit and carries no sense of context with it, you only get to see one short event or part of an event. There is no second voice explaining your side of things. No one tells the audience that the person being recorded is an 18 in a class of 16 year olds who knows that next year he will be the nineteen year old surrounded by year old junior and then the twenty year old senior. That could mess with the character's head and completely change our understanding of the story. Images rarely carry context with them. Images are readily gathered. Be aware of the image you present.
