I'd buy a copy. You don't know me and I don't know you. But I pick up your feed and read it. Why is that? I don't know, but I can tell you of the 55 million feeds (thereabouts) out there I like yours. So that means you're readable, and more than average interesting. I friend of mine just printed one single volume of a 12 year literary project at Lulu.com. He held it in his hands. He says is was a pretty incredible moment. Say what you want about vanity publishing, its the start of a product. He is going to give it another edit, but this allows him to release that copy to editors to get feedback. The presentation should make editors take him seriously.
