How Yelp is killing chain restaurants.

It's short but I thought everyone here would be interested in this. Maybe set off a good discussion about chains. Has that ever been discussed here?

KIDDING!

"Three big findings: First, “a one-star increase in Yelp rating leads to a 5-9 percent increase in revenue.” No surprise, good reviews help restaurants. Second, this mainly affects smaller, independent establishments. A Yelp review has no effect on an individual chain restaurant like Applebee’s, presumably because people already have firm impressions of those places."
