I've read such nonsense about teaching, and teaching in China on this particular forum.

Haven't we all? No big deal - discerning readers have the ability to seperate the wheat from the chaff. IMhO, this particular forum is the best of the EFL forums as it is moderated by people who try to be impartial. Reading some rubbishy posts and small talk is a small price to pay for the occasional pearl of wisdom that one can stumble upon as a regular reader. I also think that this forum is especially useful for newbies to the teaching game, as is of course its sister forum, the one about recruiters, etc.
