My top two favorite sites were definitely YouTube and TeacherTube. I'm a big advocate of YouTube because you can find a video of almost anything in the world on one single website. It's absolutely awesome! TeacherTube was useful because it has a plethora of videos that are geared especially for classroom use. I had never heard of Blinkx before 11 tools, but I really enjoyed the fact that it pulls videos from over 150 video sites and compiles them into one search engine. It made my life 1000 times easier! :)
I didn't post videos that were very relevant to my content because I teach multiple contents, but I think they pertain to education and technology, or what you make of it!
From my understandings of the Copyright Issue, feel free to correct me if I'm wrong, I gathered that as long as the information/material is used for educational purposes and copyrighted material is not being published to the general public, then there shouldn't be any issues!
