I'd be happy to post their comments about this Polish teacher and how his spoken English is 20 times worse than his written English. The web page is a fine example of an inability to grasp the language.

Very interesting! You see, I had started another thread in which I mentioned my observation that foreign teachers working for training centres in China often posted on the board using inferior English as compared to that of other posters. I wondered whether one could assume that as a rule their teaching, and of course their spoken English, would also be worse than that of other posters who were teaching EFL in China, but not at training centres. Your information re the Pole seems to support my hypothesis. But of course, one swallow doesn't make a summer!
