There is a lot of discussion as to what is going on in the publishing world and what makes a 'real' book and what constitutes marketing. Words like epub and social networking float around as much as Big 6 these days and if th Big 6 don't get with it they'll go the way of the dinosaur faster than say a current format of Facebook.
There are a ton of e-pubs out there and there are a ton of organizations in the writing world telling you print is the only legitimate form of publication. DON'T YOU DARE LISTEN TO THEM!
The fact is both forms are completely legitimate. But I've decided to take the electronic route with MuseItUp Publishing. And I love it. I may get an agent in the meantime but I couldn't ask for a better publisher period. The place is like family and is urber supportive. I suppose it is easy when everyone is playing on an even field, but coming from a filmmaking background I know that just because you're one of the 'boys' doesn't mean you're going to be treated that way.
Some other organizations you might want to checkout too are Savvy Authors and EPIC, EPIC is the Electronic Publishing Industry Coalition. Savvy Authors is an online writing group which offers workshops, chats, and conferences throughout the year. EPIC is $30 a year as is Savvy but they're invaluable with the tools they provide.
How do I promote an e-book? Honestly you have to start your platform from day one. You're selling yourself, and if you don't get out there and do it no one else will. You're platform is who you are. I'm a writer and indie filmmaker who gets angsty and passionate when people don't listen to her lol.
Bare minimum (and I'm quoting Christine Bell on this) is email loops, a website, twitter, facebook, and a blog. I've always had trouble mastering this. But I finally opened up my ears and started listening. Lea Schizas recommends one hour a day or one day a week on the self promotion.
There you have it folks. Take it for what it is. I hope this is helpful.
