Insects don't sound too appetizing to me, either. However, as I mentioned in my previous post, one huge difference I see between insects and lobster/shrimp/crab is that with the latter, we don't normally eat the shell. (Some people actually do eat whole shrimp, shell and head included.) Instead, we pull the fleshy parts out of the shell and eat that. With modern-day insects, this generally isn't convenient or feasible, because most insects just aren't big enough to do this. I suppose it's possible with those gigantic beetles that are the size of some people's hands, but certainly not with crickets or grasshoppers. Having to eat the entire insect, shell and all, would make the culinary experience quite different I think.
