For my day-job (and according to my Visa) I teach what is listed as "Oral English," which is basically a class where Chinese public schools expect a foreign teacher (who they automatically assume has no credentials or any idea how to teach, because I'm foreign - never mind either of my twin Masters Degrees in Ed or my 440 hours of post-certification instruction) to keep what is laughably called an English class entertained and out of the way for an hour each day.
The bulk of my income (and my only real job satisfaction) comes from tutoring after school, where I teach beginner Karate, voice, saxophone, Western Literature, theater, and Cambridge Test Preparation (about two classes of each per week).
I also find time to be a student: I'm studying more advanced Karate (the black belt exam is about a year off) as well as studying the Tagalog language (my children's first-language) and Russian, though I'm not very good at foreign languages.
Anyway, yes I do seem to notice that reviews are more popular. I definitely will be dropping more of them here. It takes a week to write a political analysis (at least with the number of sources I like to cite) and only about an hour or two to write a book review, so it will be a good way to get a little more exposure.
