I didn't know where to put that subject so I decided to put it on general. Do you think that YouTube is a good way to learn Japanese? There's a lot of practises on YouTube to learn people basis of japanese language.
If someone wants to learn how to count to 20 for exemple:
We can download the YouTube video, put it on a CD and create a CD with many YouTube videos...
I'd say if it works for you, go for it. Of course, anyone can post videos on youtube, so some info may not be accurate, but that is true with anything you get from the internet, I guess, including this very forum. Good luck!
