Posting this link mainly for the talk by a lady from my neck of the woods, Linda Gillard, who was a traditionally published mid-lister. She's now e-published very successfully and gives a very interesting perspective on why she wouldn't go back to trad.
Sound quality is a bit off in places, but well worth a listen - she's on at 28 mins for about half an hour.
