I always try to make a sign to acknowledge their presence. Not usually a wave, but a slight lift of my hand or just lift of my fingers from the hood or bars on the passing side. Sometimes just a nod of the head or something else just so they know I see them and many do something similar that lets me know they see me.
However if it's a time of many other things getting dicey, then I'll skip the pleasantries in favor of maintaining full control of my situation.
I find that many here do acknowledge, whether walker, jogger, runner, or cyclists. Sometimes others don't acknowledge, but I think that is because they are more worried about their safety and think that responding opens up a way for a possible attacker to pounce on them. They usually go by with eyes and heads turned the other way, which seems the wrong thing to do if they truly are worried about being attacked.
p.s. Jim, you are really overdoing the nested quotes thing. Just make a response and be done with it. I actually have no idea where you stand on anything because of your over use of them so I just don't read your posts.
