The problem with TwttrList, though, is that there doesn't seem to be any way of adding tweets that are more than a couple weeks old. Unless I'm missing something. Anyone know how to add older tweets?
An interesting discussion over there, and I think those who've commented already (including you) make a good point. Book bloggers aren't necessarily aiming to write newspaper-like book reviews. It's ridiculous to compare blogs as a monolith to professional reviews. As for the back story, if it's a blog I follow regularly, then I'm very happy to read the back story, because I'm interested in the blogger, not just the book. Actually, if it isn't a blog I follow regularly, then I'm fine with reading back story too, it just won't mean as much to me.
