Yes. I have 6 cats, and 5 of them don't bury their poops. All I can figure is that, since they're indoors and safe, they don't see the need, because they don't have to stay safe from predators (my interpretation).
It doesn't bother me. When I'm at home, I scoop right after them. When I come home from a 10 hour work day, it is a littler smellier.
