Click on the YouTube link to watch a funny library commercial.
It was fun to search for streaming videos, I have used YouTube before, when setting up for a professional activity day for teachers. Our vice-principal showed a couple of videos relating to the topic of differentiated learning.
I think YouTube is especially popular with the young people. I have noticed in the school library that many students use YouTube not only for fun but also for educational use.
I will use YouTube. I would like to set-up a library blog and use an appropriate video in promoting the school library. That's just one use that comes to mind but I am sure I could find lots of other uses.
