YouTube

YouTube-I don't know anyone that hasn't used YouTube at least once.  YouTube, for me, was just a way to look up silly videos of people.  It is very easy to use and I have used it before to upload a camtasia video for a class in the Fall of 2011.  Despite using it for education, I believe there are too many distractions associated with YouTube to be an effective educational tool.  If there were a way to set limitations within YouTube itself, then maybe I would consider using it more often.  There are other video hosting websites, but none really if you consider the amount of traffic YouTube experiences regularly.
