Agree with you, I think his skill is even worse, kind of superficialness, Just think about it, he is not a master in MS technology(he mentoined this half a year ago, he is not good at C++),as a contractor, I don't think he'll go into detail with different companies' Java, except sun's.
Actually, sun's java is definitely not good in every aspect. So what kind of architecture can he show us?
