Its what you make of it really.
If the diagram is in a tutorial, then by all means show the chip diagram.
But if your discussing how the circuit works, or proposing a new circuit,
then it only makes sense to use the schematic representation.
If people cannot figure out how to build the actual (new) circuit from the
schematic, then they can wait for a tutorial. Matching triangles to pin numbers
is not high art.

Do you really think that the diagram presents that much of a barrier?
Its no harder than learning to read a map after all.

I propose that if your discussing circuit operation, give the schematic format.
If
its strictly a tutorial, then use the physical representation.
Both diagram formats have their respective advantages for different uses. We may
be trying to introduce electronics to beginners with basically flakey circuits,
but lets not coddel people here.
Only the most popular circuits should be presented in the physical representation
in
my opinion. This way beginners can shuffle around the inverters to better fit
the circuit
into their own creations, and more advanced builders can ponder that much needed
modification or improvement.
