I have been writing reviews on mouthshut for more than one month and whenever someone rates my reviews, it feels good. Rating reviews increases the value of any review and can help the readers to make far better decision about any product.
There are hundreds of people who express their experience about any product, they might not be correct every time, so rating the review by other people makes that review more effective and shows that to what extent that review to useful to others. Its a great initiative by mouthshut that will help millions of people to take better decision.
