Addressing your concern about 'repackaged articles', the 'Hyperbole and a Half' book was in the same situation. I really just bought it to support the blog, but I really enjoyed reading it. Even when though you've read half the content before, the distance of a few years and the feel of paper make it an enjoyable experience. Plus I've been able to loan it out to a few friends who wouldn't otherwise go and read through a few years of blog posts.

I will be buying this book too and I expect the same enjoyment. If only I had a pleasant, crackling fire!
