Guy Kawasaki has a post
on what a great product is.
One of his specifications?
A great product is deep.
“It doesn’t run out of
features and functions
after only a few weeks of use.”
An author once told me
that every novel
should leave the reader
with questions
the author never posed.
It should be deep.
It should live on in the reader’s brain
after the last page is done.
That is why Fan Fiction exists.
Does your product have layers?
