"Seventy Signs of Intelligent Life on You Tube"
"Smart video collections keep appearing on YouTube. But rather antithetical to the ethos of its parent company (Google), YouTube unfortunately makes these collections difficult to find. So we’ve decided to do the job for them. These enriching/educational videos come from media outlets, cultural institutions, universities and non-profits. There are about 70 collections in total, and the list will grow over time."
Wanted to share the link with you as I am a big fan of you tube. It's great if you go searching for something in particular but I am sure knowing how to link with collections will expand its usefulness.
