It would be a service, I think, to gather some success stories showing the process of turning long-running blogs into books or ebooks. You'd want to ask about the process the particular writer went through, how much material went from blog to book more or less unchanged, how much was substantially revised, how much was new. You'd want to talk about how to organize a large body of content when some of it was produced piecemeal, without organization, possibly before the book was even dreamed of. Maybe there would be insights to glean about what blogs do really well and how that overlaps, or not, with what books do well. But down deep you'd want practical, practical, practical--how to carry it off. I have one writer in mind who might agree to an interview. You might be able to think of others.
