Recommended article with focus on C++11:
An introduction to C++'s SFINAE concept: compile-time introspection of a class member (Jean Guegant)
As a learner of C++ Template Metaprogramming a few months ago, I would still recommend to read this book.

However, in practice, I find this quite difficult to use, because of the One-Definition Rule and SFINAE. This is why this book is important, because it goes over the basics.
If you use C++ templates substantially in a cross-platform library, you will need to test-compile your code in different compilers. This is because each compiler has different level of compliance to the C++ specification. Code that compiles fine on one may be reject by the other, and occasionally the compiler that accepts it is the one that breaks the specification.
