Just to add in a bit more to what I said earlier, if you get it to the book stage, you could also ask for people to contribute to a gallery or guest tutorials etc.. to give your book more unique content that is separate from the blog. Look at Vertex as an example.
Cool, thanks guys. Vertex is awesome but I think it was more of a general game art book. This will focus specifically on real-world construction details that are often missing or done incorrectly in games. I will definitely be looking for feedback and critique. I've decided that the test chapter will be emergency lighting…
