No, they aren't. They are highly related to teaching and other relevant aspects related to it. I admit that hints on watches etc. could sometimes also be useful for teachers, but the scope of the latter is obviously more limited. For the topic on Chinese women, the same basically applies because for (male) foreign teachers in China, it may be an an important aspect of their practical life. However, the are only helpful and would have some value if they covered some sort of sensitive cross-cultural analysis without undertones of racism, sexism and references to brothels, hookers and the like. That's my stance on the matter; and it hasn't changed.

Some people would say your pics of your trip to Nepal are useless.
