You almost never use base_init() and your tutorial would better tell
people to use class_init() which is what almost all of the code out
there is doing (disclaimer: I didn't read your tutorial). I haven't
yet seen any code that uses base_init() so I can't tell you what it's
good for.

Simply so that it inherits whatever is in the parent class. There
needs to be a copy so that a derived class can override functions
without changing the parent class.

Please don't call it madness unless you understood it completely and
are able to judge. If you continue to rant on the GObject
implementation it is very likely that you won't receive any further
answers to your questions.
