I guess if the online reviews of my shop were all unconditionally positive, I would love the idea.

Alas, they're not. So I, too, will be critical.
The overt purpose of online reviews seems to be to create uncensored community feedback on local businesses and services. It's like word of mouth magnified by the power of the internet. If you do a great job, people will refer friends to you, if you tick them off, they make sure the whole world knows about it.
In principle, this makes perfect sense. In practice, I see a few serious drawbacks.
First, a great many people still don't know their way around those social bookmarking sites, or don't care to use them, and though they may be thrilled or disappointed with the service you've provided, they have no way to tell the world about it. For example, Rapid Transit Cycleshop has less than 30 total customer reviews on Yelp, while we service more than a hundred paying customers just on a typical spring weekday. Many of those customers have been coming back for several years, and a handful of those that do have written positive reviews. Like this one: "The folks at Rapid Transit truly value me as a customer. I've bought
bikes from there, and they've bent over backwards for me on countless
occasions. Plus, they have the most competent, trustworthy bike
mechanics. Over the years, Rapid Transit has made me glad I own a bike
instead of a car. They're not in it strictly for the money, but
they've clearly succeeded over the years. They're true advocates of
bike culture." Many others either keep the good news to themselves, or use traditional word of mouth.
Second, there is no way for a business to respond to and correct grievances. Got a gripe? Please bring it to me. The sign above the register invites you to bring your purchase back for a full refund or exchange if not completely satisfied, and we have honored that policy for many customers on many occasions, whether poor fit was a problem or simply a change of mind. When we are informed of the problem, very often an unexpected solution, and even increased mutual respect, can grow out of the dialog. This venue has no room for dialog. It's a good place to lodge a complaint, but only if you don't want to find solutions.
Third, comments that are simply hateful or even obscene. These are perhaps less of a problem from a business standpoint, because I imagine that most readers of these reviews will simply draw a circle on their foreheads, and ignore them. Think for a moment about the blood sweat and tears you put into your work every day. We, as shop owners and personnel, work in the public arena all the time, dealing with people's good and less good moods, and good and less good days, often providing cures for more than just their broken bikes. We get pretty thick skinned. But there's no other way to say it: that stuff hurts.
Fourth, well... enough already. There is simply no accounting for taste, preferences, personalities and other intangibles. What to one person seems like a high-end bike is basic transportation to another. A week may seem like a long wait for a repair, but not if it's May and you've called around and found that other shops have a three week backlog. An expensive tune-up to one customer may be a life-saving operation on a beloved bike of another. What frustrates me about online reviews is that they are a one-way street. So I'll end with one that goes the way I'm heading: "Lots of bike shops sell bikes. Rapid Transit sells bike commuting."
Well, that's my take on it. But it you feel inspired, go ahead, and take a lob at us on Yelp or Chicago Bike Shops, or wherever. (But, really, couldn't we just talk it over?...)
