I hate them. I wish they would expire after some reasonable period and disappear (both good and bad) as a review for a restaurant that is from 2 years ago is meaningless. We take thousands of orders per year. On the major review sites (don't want to name them so this thread does not come up in search). We might get a few dozen reviews in a year? So, between them we get about one review for every 500-600 orders and guess who tends to review?
