I continue to be thoroughly whelmed by Scalzi's novels. He has great ideas, but there always seems to be something lacking. Based on this, I think it might be that his plots aren't nearly as interesting as his worldbuilding. Lock In has a lot to recommend it - a clever setup, a well thought-through world, some neat touches (a narrator whose gender is not only unrevealed but completely immaterial, and you barely even notice it)... and yet I find myself vaguely annoyed with the murder-mystery plot and the endless technobabble.

Maybe I should just stick with his blog and twitter feed.
