As long as every registered member is free to rate, J2O ratings should never be taken seriously. Due to that I personally see no reason to change such a small aspect of the rating system as is the scale, instead of for example creating a "council" which could give downloads a separate, unbiased and allowing comparisons rating. Every download could then have "regular reviews" from normal J2O members and "professional reviews" from council members. Then there would be two total ratings, a "professional rating" being an average of professional reviews, and a "total rating" being an average of all reviews, both regular and professional. This is my opinion on what could really lead to meaningful ratings.
