When ratings are positive, everything is great. However, ratings can be problematic and unfair when they are negative.
At MyMindshare, negative ratings aren’t necessarily a value judgment on the worth of a bidder’s web page. A negative rating simply means that the bid isn’t being targeted to the right people.
The rating system at MyMindshare is a 1-5 scale where a thumbs-up is a 5 and a thumbs-down is a 1. The rating is simply an average of all the thumbs.
In order to treat poorly rated bids fairly, a minimum of three stars is displayed on the site. It’s our opinion that showing less than 3 stars creates an unfair negative bias toward the bid. So even if a bid has a 1.0 rating, the bid will appear with 3 stars.
Even though the stars are a 3-5 scale, the rating is still a 1-5 scale, and the bids are ordered by the rating. A bid with a 1.0 rating will have 3 stars, but will appear at the bottom of the list.
