You are right, mscollick, I agree. There is just one problem, though: not always those that prepare videos and send them to YouTube or anyother similar site, are real teachers with real knowledge of the teaching of English. Yet, there are others that are a blast, I personally know some and your advice is fair enough :)
In my modest opinion, the learning of English, or either the "brushing up" for native speakers only can be acquired when there is a bit of everthing. There is nothing compared to a book, with the possibility of writing or exercising, and also the use of computers for that purpose. The combination with visual-audio material (videos, music, recorded texts, drills, etc.) AND printed plus visual material are the ideal recipe for a good reinforcing, reviewing and even learning from the beginning of any language.
Good luck, everyone!
