This book is a collection of 52 essays representing some of the best science blog writing from 2008. It includes essays from a lot of the usual suspects, plus others I bet you don't know. My own post about WR 104, a potential nearby gamma-ray burst progenitor, is in there too.
Open Lab 2008 is on sale at Lulu.com for $15.50, or you can download a PDF for $7.50.
I have both Open Labs 2006 and 2007, and they are wonderful book full of good science, skepticism, anti-antiscience, and just plain old good stuff. I really recommend getting a copy. My congrats to Bora, Jennifer Rohn, and everyone else who worked so hard on this.
