Today I am resting and editing my blog-book that I am making (by the year, so it's really about 5 books...) I am using Blurb's Booksmart to download the blog entries.
It's an OK editor -- you can't save it as anything but their propriatary file format, though. And the text editing functionality isn't so very great. But at least this way I can 'slurp' my blog into printed format and save the files on my computer.
