I'm about 1/3rd into tGH right now, and with the exception of Egwene being awful, I really haven't had much to comment on. I know there's some things I've missed in EotW, and there's a couple minor things so far (was someone actually watching Rand when he was trying to escape Fal Dara during the Amyrlin's entrance? And if so, were they channelers, since they seemed to be able to travel? And if so, was it Ishamael?), but I'm really awful at A. picking things out to ponder over, and B. remembering the few things I actually do pick out.
So for those reasons, I enjoy reading other people's notes more than coming up with my own, since I notice more when other people mention things, than when I think of 'em.
