PopTech just sent me a book of quasi-interviews to mark their 2005 conference, and it was a Blurb book. It was, in other words, created via the new Blurb service via which you can experiment with DIY book publishing.
My verdict? Nice work. The binding is well done, the paper quality is great, and it generally looks professional — other than the title on the back of the binding, which is the same font and color that adorns my decaying Ph.D. thesis. Whoa, flashbacks.
Some good stuff in the book too, by the way.
