Chris, I tend to agree with your view. Recently I had a number of ontologists and domain experts working on a project. Many of these ontologists were seasoned veterans who had worked on logic programming, FOL-based, and other logic-based KR systems -- but not description logics. We had to go through a (short, thank goodness) retraining period so they could map their logical constructs into the terminology of description logics and frame systems. I would personally much prefer standard logical terminology, but have learned to map, so it is not a problem. But the de facto standard today I think is and should be logic.
