IMHO you're absolutely right -- but it applies to any newsgroup!
On the other hand, ..., well, wait, I'm not opening that can.
But on the third and gripping hand, while the opinion that I think
triggered that blast, "don't derive from concrete classes", may not be
the world's best advice, it is a practice that works for some kinds of
problems. For example, original COM was built on something very
similar to that idea, "don't expose derivation from concrete classes
to client code". But I think that even that more limited idea was
shown to be too drastic, when COM+ did away with it. :-)
