Bora Zivkovic over atthe collective Science Blogs has done something incredibly cool: he looked over hundreds of science blog posts from the past couple of years, winnowed it down to 50 (with the help of a lot of friends) and created a self-published book called "the open laboratory: The Best Writing on Science Blogs 2006".
The history of the project is a good read. Bora is obviously dedicated, cool, and slightly insane. But he made a lot of very good choices: I've read many of the blog posts in the book, and they are excellent.
In the cause of full disclosure, I must note that the very first entry in the book (minus the forward) is, ahem, my Science Fare post. I am very, very honored and more than a little proud to have it included.
Anyway, Bora went through a lot to produce the book, so you should buy it. I make no money from this, and I have no idea if Bora does or not (though he should). I'm getting a copy for sure.
