This is good news for all authors, including, let us hope, indies. Not such good news for traditional publishers, booksellers and agents though.
This just goes to show that the world of writing is in greater turmoil than at any time since, well, you choose the dates: the invention of printing, perhaps?
Personally I think that what is happening is akin to the infant phenomenon that was Dickens writing and publishing Pickwick Papers and Oliver Twist in cheap, monthly serial form. He was told that such a move would be the death of his ambitions to be a man of literature. He chose to ignore this advice.
Good on you Kobo.
