Ahem, actually the "product" is advertising slots which play during Friends.

But it was a nice rant Alec.  I agree that we need to avoid "overmodeling"
and allow individual domains to evolve naturally.  In general, generalizing
is easy, and easy stuff shouldn't hold up hard stuff (ie. actually loading
useful data).

One problem with this stance is that we don't have an answer, let alone
an interface, to the schema evolution problem inherent in post-hoc merging
of "similar" types.  How do people specify this, and how do we execute
those specifications *without breaking applications*?
