    Steve has been the partner on a number of acquisitions for Yahoo that I have worked on and he's been terrific. He is able to give excellent advice as to what to focus on and what is not as material and he provides a vast wealth of knowledge and options when trying to think of constructive solutions to thorny issues. He is also an excellent in person negotiator.
