I really enjoy using this website. I work hard and use several resources. But I think that the move to all Chinese in the intermediate levels is counterproductive. I'm giving it a valiant effort, but what was once fun and informative is now like the cartoon of the dog Ginger listening to her master and hearing "Blah, blah blah blah Ginger blah blah blah...".
I use the podcasts as just that; I download them and listen to them away from my computer. The result is that I can't understand most of the dialogue, and only half of the comments. I try to pick up a word or two, and I understand the immersion theory, but the transition is too abrupt. Perhaps designating a low intermediate with a little more explanation would work.
I suspect that you lose a lot of elementary level customers when they find themselves on the sidelines after they hit intermediate lessons.
