Welcome, Fabien.
I don't consider myself to be leprous or a pariah because my book is in the process of self-publishing. Doing everything myself has given me a better understanding of the publishing process, including typesetting and cover art creation. It's also added to my skillset as a graphic designer, which might come in handy in the future, who knows. I like having complete creative control over the process, which allowed me to get creative with the cover design in ways that a random graphic designer might not think of.
We are seeing a major shift in the book publication industry, just as in my own industry (I"m a newspaper reporter). Paradigms are shifting like the San Andreas fault.
I had a discussion with my editor at the paper not long ago after we covered an event featuring local authors and one local "publisher". She was trying to encourage me to talk to the local publisher about my book. She said she wouldn't do an article about a book that was self-published and made a sneering remark about vanity presses.
I'd already looked at the flyers they were handing out. They charge money to publish books. Judging by the books they had on display at the event, whomever is doing their graphic design has no talent and few skills. Once I explained that to her, she realized that she'd just tried to pressure me to use a vanity press that charges a lot of money to publish books, instead of CreateSpace, that costs almost nothing to use.
I also covered a visit from a writer whose book, the Shack, was originally printed at Staples, and then self-published by some friends of his who set up their own publishing company just for that book.
At the time (a couple of months ago) he'd sold many millions of copies and it was translated into 14 languages.
Anything is possible. The publishing industry is a crapshoot regardless of whether you have Doubleday as your publishing, or a couple of buddies shipping books from their garage.
Welcome,
