As pointed out by Christina, already in 1983 did Schubert, Glänzel and Braun normalize citation counts in a similar fashion. The crown indicator is just a further refinement of this idea: divide the average citation count for a group of publications by the avergae for all publications of the same type, in the same field, in the same year. The main difference is that these older indicators typically use the mean citation rate of a group of articles as the numerator, whereas Radicchi et al. apparently use the number of citations for an individual paper. This has recently (and, as far as I can tell, independently) been proposed by Jonas Lundberg. Still, the PNAS article certainly has some interesting contributions, so I don't want to imply that it has no merit.

WRT voting - I saw an article in one of the ACM or IEEE magazines where that was a suggestion... can't remember where now.

While I don't want to discredit the authors' work, I would venture that the idea in itself is not so new. Is this type of normalization not very similar to that of the CNTS ‘crown indicator’?
