Far be it for me to defend Isaac's often less than enlightening posts on LuLa. But consider the situation Isaac appears to be in. It's pretty clear he's a cripple of some sort. Isaac is very interested in photography, but he doesn't post photographs, which implies strongly that he can't get into a position to make his own. He seems to be widely read in photographic literature, probably a pastime imposed by immobility. It's not hard to imagine that someone fascinated by an artform, but physically unable to attempt it would spend time making waves on a blog such as LuLa in order to say to the world: "Here I am." We probably ought to go easy on this guy. He can be very irritating but sometimes he comes up with something that starts a worthwhile discussion.
