Additional: In the spirit of openness, I will remind everyone that you can read the book for free by following the links here. Inconvenient compared to a nice, unified, cleanly typeset, high-resolution, portable compilation, if you ask me.

In a few weeks, the book will also be available at other online retailers, e.g., Amazon.com, but we prefer that you buy from Lulu.com as the proceeds will go towards organizing ScienceOnline‘10 next January.
ScienceOnline is a science blogging conference. Next year’s will be the fourth such event. Of course, people blogged about it at length, but a very brief intro to last year’s is here.
