Google returns about 18,000 sites with the word bookblog, but to me it means posting your impressions on each chapter, as you progress through the book. Obviously something like this works better for nonfiction, and particularly for mostly-unrelated collections of vignettes like Bryson and Gawande have written. But with running commentary from the blogger and their devoted readership, it'll play like a book club in motion, chapter by chapter.
Two things that have intrigued me so far about Gawande's book are his experience on Friday the 13th, and his thoughts to medical error. I'll tackle them tomorrow, methinks.
The Friday the 13th he describes had to be in March 1998 -- because it combined the 13th with a rare full moon AND eclipse. You don't see that much anymore.
