Re: publish and be damned?
Yes, just to clarify, I'm not suggesting that everyone is able to afford a full novel line edit.
However, there are plenty of options - editing of first few chapters shows simple mistakes you can correct yourself; joining a critiques group helps with feedback; proper research of the story themes; proper research on how to write professionally; etc
Much of what people need as a writer is free or relatively cheap - an editor may cost, but that is probably the last thing on the shopping list.
The trouble with self-published writers in general is that they don't even start with a shopping list of things to do to make their MS a good standard!
