You might have seen some of Daniel Floyd's games design videos on his YouTube channel. This animation student has earned himself quite a following and a reputation for intelligent and entertaining video-lectures. They're all suitable for non-gamers, too, without being at all dumbed down which is quite a feat.
Anyway, Floyds has himself a new Blogspot blog, Talking About These. He's already got a couple of thought pieces up there. I wouldn't be surprised if this becomes a favourite blog of many - keep your eye on it.
