All I would say is that (apart from egg cups for lizard eggs [which I notice is missing from his list :-) ]) it is not possible to give anything a zero rating unless you personally believe it isn't true. Belief has no place in an objective list.

I am not saying that he is wrong, that would be just as wrong. All I'm saying is that there is a definite trend in the ratings, which points towards personal opinion. That's ok though, because we will probably never know and speculation to spark debate is necessary. The danger is that any list like this becomes accepted as definitive.
