Probably we do it all the time - and not only with sub classes but
with completely unrelated classes (-> duck typing). :-)

IMHO you used an important word: "buzz".  These principles have their
value where applicable but should never be followed religiously. It
does makes sense though to reason about them and understand their
value so you can judge when to apply and when not.

Another reason for the observed lack of "buzz" might be that the Ruby
community generally seems to be more focused on getting things done
and not less interested in, err, theoretical debate than maybe other
communities. ;-) (Which, btw, does not mean that there are enough
people around here with brilliant ideas and excellent solutions.)

Just a few random thoughts...

Kind regards

robert
