The next of English Teacher X's ebooks that I have read is subtitled An expatriate guide to not getting robbed, scammed, jailed or killed. In pre-Skype days, I was living in a place in SE Asia where the internet was expensive and used to use an internet cafe across the road   Most days I heard someone phoning home to ask their family to send them some money as they'd been robbed. The risks he's talking about are very real, and the first part of the book makes a lot of sense.

There have been a number of articles about the growth of ESL teaching in the Philippines like this, but some of what they are stating don't strike me as right. The Philippines does have potential and in the drive to reduce costs, it is clearly a place to watch out for.

A few years ago we used to host some pieces written by Martin Wolff and Niu Quiang about their experiments in trying to teach English in new ways in China, which have since evolved into the China Holistic English site (link broken).

Quite a lot of people post the same question in a number of ESL forums. The logic behind doing this is clear- you should be able to access a wider selection fof views and opinions and get better answers. However, things don't always work out the way people think and this process can lead to objections from the people answering.
