Thank you for your comment. I like it a lot. It is a great way to think of inheritance. We have both seen inheritance overused by developers so it always helps to have ways of determining “good” inheritance from “bad” inheritance.

You know you’re preaching to the choir with me, but I thought to contribute one interesting idea. I think I got this from Amir Kolsky, but it may have been Rob Myers. Anyway…

One thing I look for is how they are using inheritance. Rather, what “kind” of inheritance they have put in place. One kind is like inheriting traits from your parents (I am like my parents in these ways…), The other is like getting your parents’ stuff when they die (my dad left this ring to me). We like trait inheritance (life) much more than stuff inheritance (death).
