I think it would be awesome, if you were following or followed by somebody, if you continued to watch and address that person. As it is, moving and roleplaying at the same time is a big pain in the ass. Posing resolves this issue, but not all of us are posers.
Having to move a step, then watch and address a person as soon as you can, just to make sure you don't miss something they are trying to say or do is a hassle. Don't get me wrong, I love the watch and address system, but there should be some way to give your attention to someone even as you're moving. If I'm walking side by side with someone and they grope me, I should be aware. :)
