Open Culture is one of my favorite blogs in the blog-o-sphere. Every time I visit Open Culture I find a new and interesting video or podcast. Today Open Culture has a list of 70 great, news and education video collections found on YouTube. The list is called 70 Signs of Intelligent Life at YouTube. The next time you’re trying to convince your school or IT administrators to allow you to access YouTube in the classroom, show them this collection of videos that have significant educational value.
