Although I don't agree with the article and find it to be extremely biased, it bothers me a little that if the title was "10 Reasons You Should Skip Self-publishing" probably very few would even bat an eye.
If the article were as biased as the one linked to here, then I certainly would.
IMO, self-publishing has come a long way and has more advantages than it did in the past. More than commercial publishing? Eh, I'm no expert on the subject, but I'd venture to say they both have their advantages and disadvantages, depending on what the author wants to accomplish.
I'm of the mindset that there doesn't have to be a war between commercial publishing and self-publishing. I think there's enough space (especially cyberspace) for everyone. I don't get the ongoing arguments as to which is "better" when it all comes down to personal preference.
Absolutely. Neither trade nor self publication is flat-out right for everyone: each has its own advantages and disadvantages, and so much depends on the writer and the work concerned.
In the end, no matter who the publisher is, the readers will be the ones to decide what sells and what doesn't. A book can just as easily fail with a commercial publisher as it can with self-publishing, and same goes for success. It depends on the book, and it (sadly) depends on luck.
Here I disagree with you. A book from a trade publisher has a much bigger chance of succeeding than a self-published book (if by succeeding you mean "selling in good quantity") because trade publishers on average put out a higher-quality package and reach more readers than most self-publishers manage. Otherwise, I'd say you're spot-on.
