Sometimes I go on the internet, but everyone's spelling is so bad it's depressing

Like many other 23 Things bloggers, I'm a big fan of YouTube. It's great when you're trying to remember an advert from ten years ago, or you want lots of funny videos about cats. Personally, I don't watch much 'user generated' content there, mostly because life's too short and there's just too much to keep up with. The BBC has an excellent presence, letting me catch up with little bits of shows rather than having to skim the iPlayer looking for the clip I want. The Muppets channel is also excellent, and hearing Beaker sing Ode To Joy is one of life's little pleasures.

I hadn't encountered YouTube EDU before, and I can see how it would be very useful as well, although I do wonder if it encourages students to stay in bed rather than come to lectures.

On the other hand, if your lecturer's style is impenetrable, I can see how it would be useful to be able to go over it at your own speed, and especially for science subjects, where a lecturer can fill six or seven blackboards in the course of an hour, being able to see the talk as well as hear it could be invaluable.

When it comes to comments, YouTube is fairly notorious for being just about the bottom of the barrel, even for the internet. Personally, I don't ever read them, just in case.
