One realization I have come to when talking with many other developers is that there is a good number of developers that don't realize that inheritance introduces dependencies directly into your classes. Your derived class is now dependant upon the interface and behavior of your base class. Worded another way, your derived class is now strongly coupled to your base class. I've met a number of developers that are very passionate about managing their dependencies via inversion of control, dependency injection, etc. and yet they implement solutions that have a class hierarchy 5+ layers deep.
