They could also list the most commonly used ff programs (ie the ones that attract postings in this forum), and ask voters to rate each of them on a scale of 1 - 10, or N/A, if the voter holds no opinion on a particular program. Having an area for comments would also be good. They could then publicly laud the top 5 programs, while telling each airline exactly where they placed & sharing relevant comments with them. This would be a much more informative survey than the current set-up, and hopefully the bottom-ranked airlines would do something to improve their act.

I hope to be not-so-earthbound in the near future, & will be looking around trying to decide which US-based program(s) I want to join. Having the information on the top 5 programs worldwide should indicate at least the best/second-best US programs. As it is, when the time comes, I'm planning to ask around in FlyerTalk, as there doesn't seem to be indepth information available elsewhere.
