I'm sure you're getting sick of hearing about it, but I wanted to note that some great reviews of Creating Interactive Fiction with Inform 7 have popped up online in the past few weeks. One's greatest fear when working on a book like this is that it's going to be too obtuse, or conversely too dumbed down, to be useful. It's been wonderful to hear that people seem to be enjoying the book and finding it a useful resource for learning Inform 7.
One place without any reviews yet is the book's Amazon page. If any past or future reviewers have an account there and wouldn't mind posting your thoughts (perhaps on a break from reviewing comp games?) it would be a much-appreciated way to help me a little with the book's promotion.
