Litblogs vs. book blogs

So, according to this interesting post, and this follow-up after ensuing debate, a litblog would be a blog "cited most often in mainstream media," with "a journalistic feel to many of the posts," and "a sense that the blogs were, and still are, a jumping-off point to professional writing." A book blog would be a community blog, with emphasis on the discussion of books by passionate (if not numerous) followers. Speaking of blogs, some rankings put Canada's own Bookninja 7th - hooray! And The Guardian Book Blog at 13. Hmmm... is it their ugly logo?
