In hindsight, after my initial post, I realized that he has been around long enough to have maybe had some experience with clipless pedals. Making the assumption of ignorance was possibly inaccurate. Interestingly, the time period he said he started using them is the same as mine (and probably yours). There seems to be a lack of awareness that other folks have also been doing this cycling thing for a long time, have had lots of different experiences with different things, and have done their own research.
