All about vanity publishing
In the old days it used to be called vanity publishing, these days they prefer to call it self publishing. Either way the result is the same - the vast majority of "self published" stuff is unmarketable garbage. I expect that most purchases are made by people who wrote the books in the first place.
I think the only reason that Amazon, Lulu etc. even offer ebook & DRM services is because its another way to nickel and dime the deluded and vane on their way to the checkout.
I realise that occasionally there may be reasons to use self publishing, for some technical document or niche subject or whatnot, but by and large its an ego trip. Even for a niche subject I do not understand why people would use a self publish service when most of them deny the author the right to set the price of their own work.
