Aaron Wall is struggling with the forces of the publishing world, who’ve re-nigged on their original agreement to let him maintain e-book publishing rights if they take his book to press. Aaron has a lot of positives and negatives on both sides of the equation, but the heart of the matter is who will have control over his book moving forward.
My personal opinion is that Aaron should walk away from the publishers and self-publish SEOBook, but there’s a good bit of discussion. It will certainly be interesting to see what happens to the “legitimate” SEO world’s most famous author.
