I doubt that. The super-star projects with millions of users sure, but the majority of OSS is probably in the long tail of tiny one-man shows, Github projects with five stars, etc.
The small one person projects with 5 stars have nothing to do with "operating in some sort of strict high score board fashion" or meritocratic evaluation of anything.
Anyway, FOSS makes yearly polls about these topics. It is biased toward more involved projects, but again I don't think someone's one weekend demo is what is talked about here.
