Personally speaking,I don't look at who's viewed me too much, because I don't think that who's viewed me is necessarily interested in me as a prospective partner, I've noticed,that if I post a lot, i'm viewed a lot, by both men and women, but I understand if you attach importance to being viewed then arranging them in order of who has viewed you most recently would be of benefit!.
I only pay attention to the nods
again, just a personal view
