Ha Ha Ha, Ya vivek you are gettin too many ideas these days. Well ya you mean the review ranking and voting pattern the way its in yahoo answers? Yes true, its a good idea to implement it. Also the reviews should be displayed in the order of its ranking. So, that users get the best reviews to read. Also, the quality of reviews will be better. And infact there should be some extra points for the best reviews. Then, members will try writing better reviews rather than packing up everything in a few lines just for the shake of writing a review.
