The idea is for one large interview to appear (cut up in pieces like Osiris--to be eventually collected like Osiris as well), sprinkled here and there over the web. To put it another way (without that troublesome Osiris), your question will appear in three ways: on your blog, along with my answer; here, as a question only but pointing to your blog; and lastly as an item in a round-up Table-of-Contents post (also linking to your blog.)
Along with the piece of an interview, I'll ask you to post some information about the book--an image, some comments, some information. Note: you don't have to be an author or have a blog that focuses primarily on books. In fact, I think the idea of having launch posts on all sorts of blogs is a fun idea.
Update, late March 4th: So far I have three visual artists, a novelist, two poets, and one historian signed up. And I've already answered two questions. Come play!
