The fact of the matter is cash. The fact to all life is CASH. Many established writers are self-publishing for that fact. In the past two plus years I started this folly money has been scant and many publishers who have owed me money have gone belly up leaving me like most creditors: pant-less let alone with empty hands with turned out pockets.
Still the stigma of self-publishing persists in some circles; in smaller concentric circles as technology and the economy change perhaps for the worse.
'Vet your publishers' truer words have never been spoken but in these times everyone is hurting.
