This is great and simple.
It may be enough to kill this blog.
It's been nice knowing you.
I love Adrian Underhill who is of course the author of Sound Foundations one of the most helpful books for teaching teachers and students about how their mouths work and how pronunciation classes work.
This won't put him or us out of business. This will just make teaching English a hell of a lot easier when you have the internet in the classroom. Having a great resource doesn't make better teachers but it does learning to be a better English student and learning to be a better English teacher much easier.
And that's the whole point, isn't it?
