If it's working for you on the self-publishing route, there's no earthly reason to stop. (However, dealing with the t.v./film people, you will definitely need an agent or film lawyer. They are not kidding around with those contracts.) The simple point of a partnership with a publisher is to achieve certain goals that the publisher can help with, which can be anything from placement of print editions in odd places like airports to multiple country launches on a solid scale to taking over functions that are keeping the author from being able to write. But if you are achieving your goals without the publisher, then teaming up isn't necessarily the path you want to take, or maybe take with some projects and not with others. (You might, for instance, want to self-publish adult works and work with a publisher on YA or kids projects to get into the schools more effectively and widely.) If you are only e-pubbing, you're selling to a smaller, more restricted audience. But if you're selling to 100,000 of that restricted audience, that's not necessarily a hindrance. If you're only doing it on Amazon, that's a big concern, but the market is opening up way beyond Amazon. And POD is doing interesting things. It's a lot of work, doing the shipping, etc., but some authors are willing to do it and it works for them. The important thing is for authors to stop feeling guilty. Authors working with publishers should not be made to feel guilty for doing so. Authors self-publishing should not be made to feel guilty for doing so. But there are, unfortunately, some financial rewards some people can make out of doing just that. And so we have this other fake war of words going on.
