YouTube science videos - not exactly sterling

This YouTube Cell Biology video has a five star rating. It was uploaded in 2007.

Uploaded in 2007, first recorded in 1981. It's not a biology video, it's a history of science video.

This isn't atypical.

I'd ask Google to give us a scholar.google.com for YouTube videos, but I'm beginning to suspect there are only about 20 really good science videos on all of YouTube (like this one - link is to a family blog I'm experimenting with). That doesn't make for much of a search engine.

I'm shocked, shocked, to find that business model problems are going on here!
