Here's an interesting concept that's just been released for purchase, either as a digital download or as a bona fide book: The Open Laboratory: The Best Writing on Science Blogs 2006. It's edited by fellow ScienceBlogger Bora Zikovic.
Oh, and it happens to contain a couple of posts by yours truly. In any case, it's a chance to see the best science blogging of the last year or so, all contained in one nice package.
