The 1-5 would be a rating of the specific review, if implemented. I also think that we could have a revolutionary strategy where the reviewers have yet another incentive. How about advertising revenue sharing? Not a lot of it, of course, but a small percentage of the amount of advertising revenue the specific article generates (if this is possible?) Not only would they get notoriety, free advertisement, and a community, but also they'd have a financial stake in the website succeeding.
