Seriously? "author"

For what it's worth, my comment was on a PC bent. Nowadays, "waitress," "stewardess," etc. are frowned upon, and your use of "authoress" needlessly draws intention to the distinction. It's a clumsy word as well, which makes it seem that you find this distinction notable enough to decide against the far, far more common "author."
It's probably quite baffling to someone for whom English is a secondary language.
Waitress is still very much the term in this part of the world.
Entrepreneurs who think like that often fail, because money distracts them from creating true value for users.

It's a nice story for bloggers and journalists, but I don't think she's someone I need business advice from.
