I did it. There was an article the other day in USA Today about self-publishing. I have a strange, hybrid book called Fake Quotes, Falsely Attributed that is humorous. I made up quotes for well-known people and put some of them in poetic form or forms of speech that are not typical of the speaker. I received some pretty good feedback from publishers, but no acceptances. I had submissions pending, but they are taking forever to get back to me so I decided just to go ahead.
I did it with Kindle and I had some formatting issues. Hopefully, they will get back to me and help me out. There is only a quote a page and 98 pages so the layout is a bit different. I had to try it at least once and see what happens.
