I guess litblogs or blogs on books, plays, writing, painting, and similar works are not prevalent enough to warrent notice when you look at the whole blogosphere. Still I keep hoping will point us out, and again my hopes are dashed.
The 2006 Weblog Awards (now accepting nominations) has an arts category with this list: Best Photo Blog, Best Culture Blog, Best Diarist, Best Gossip Blog, Best Music Blog, Best Podcast, Best Video Blog, Video Of The Year.
Best photo and music–good. Where’s literature or best humanities maybe?
