Any Interest in a Shameless Popery Book or e-Book?

A few of you have approached me in the past about this topic, but I wanted to open this up to general discussion.  If I put together a book and/or an eBook, would any of you be interested in buying it?  Most likely, I'd take material I've already written for the blog, lay it out in a more straightforward format, and combine it with some additional original content.

Here's what I'm looking to find out from you:

1. How interested or uninterested are you in this?  (Please, be honest!  If interest levels are low, that could save a lot of unnecessary hassle).
2. What topic or topics would you most like to see addressed?
3. What's your preference on the format?  Do you prefer traditional books over e-books?
4. How long should the book be?  

I can't promise I'll take every suggestion, but it'd certainly be helpful for me!
