Youtube blocked

I think that youtube should not be blocked or restricted from use at school. It should not be because there are some really good outcomes of youtube like it could help summerize and huge historical event that happened. Also youtube should not be considered a social networking site because all you do is watch videos and comment just like you do on a blogger site and your name is not out there you can make up a fake name. Also bennifits of youtube could help student that are more of a visual learner then a reader type or learner. This is why i think youtube should not be blocked on or for school purposes.
