In Finland, we have the concept of "donkey's bridge" which means a way to move discussion to
(un)related topic across a method that might superficially seem related but in reality is not.
I do not know where it is coming from, and I digress.
I feel like pointing out a man called Steve Yegge who tends to have useful bits of information
in his blog, especially for programmers. Give it a try, maybe his style works for you.
