1. The book's homepage looks quite old-school. This isn't necessarily bad, but may make some people skeptical, or make them erroneously think it's an old '90s page. Perhaps at least put the publication date (2012) on the page somewhere prominently.
2. It might be possible to promote the SubC compiler independently. It could be useful to various people for pedagogical purposes, and if it gets known, the book will get some indirect promotion. Perhaps write something comparing it to tcc, the other well-known small-and-free C compiler.
3. Being able to sell copies through Amazon may help sales, though iirc you do get a smaller cut of the proceeds in that case. It looks like you don't currently have whatever Lulu package is needed to get an ISBN, so the book doesn't show up on Amazon.
