Thanks, Jamie, for sharing your very helpful ideas and knowledge from your self-publishing experience. It was a really inspiring presentation, and I enjoyed meeting some other inquisitive would-be self-publishing authors, like myself.
If I had anything to add, it would the recommendation that every self-pub author invest in the Chicago Manual of Style and read the first few chapters to get acquainted with traditional publishing processes. Even though, to save money, most self-pub authors might elect to multi-task on some of the jobs involved in publishing a book, it's important to understand why publishers have the distinct positions of developing editor, copy editor, designer/DTP professional, and proofreader; and why each job has its own set of specific tasks at a particular stage of the production process.
I would be interested in attending another seminar on Web self-publishing, as a means in itself and a way of building an audience for a future print work.
Thanks for getting the wheels turning in the ol' noggin and kudos to your success!
