I wonder the psychology (of many review sites) that people are more motivation to seek out area's to post negative reviews, rather then a positive. Lack of a business "if you enjoyed our service please let us know via (Yelp, Google Pages, etc.) which may net a higher return of happy customers. I personally more inclined to hop on Yelp as a warning to other consumers on a poor business, vs, just random "ups" to other well run businesses. I gain no benefit but altruistic feelings, and this, takes time. The time it takes to post a negative review is rewarding in itself to try and "help" others avoid or be wary of said business. Also, markets should take a factor in analysis of Yelp reviews. As an example, larger cities have a much higher preponderance of reviews as a whole, where even medium (what I would call them) such as SLC (where I live) are very sparse and therefore limited in search / decision making.
