I'm confused by your point here. Are you advocating that credit for an idea should go towards the most famous person possible, so it gets the most exposure?

My point here is that Eliezer gets read plenty on the topic of cryonics, perhaps more than he should, while people like Darwin get read too little, even by people who should be reading them. Allocating credit towards Eliezer and away from someone like Darwin exacerbates this.
