The Genesis method of setting up speakers recommended by Greg closely resembles that of Wilson Audio which I use. The latter refines things a bit by using masking tape on the floor to mark the points were the voice of your speaking friend changes and by using tape measures on the floor to ease checking the small movements required. However there is one major difference in that Genesis do not recommend using toe-in for their speakers. I would ignore that unless you use Genesis speakers as some degree of toe-in is often essential with other makes or in given rooms.
