Does Your Firm Have the Guts to Seek Anonymous Client Feedback?

Mike Arrington posts about The Gorb, a online reputation monitoring service:

Gorb allows, even insists on, anonymous comments and ratings about an individual. Like someone? Hate them? Tell Gorb all about it, using their handy Ajax slider to rate them from 1 - 10 in their professional and personal lives, and leave written comments as well.

According to Gorb:

The professional marketplace in general is inefficient when it comes to distributing information about a person's reputation. Many of us often make daily decisions based on relatively few inputs, some which are poorly validated. When these decisions begin to form the basis for our perceptions about others that we don't know, it should be no surprise that there's a hit-and-miss nature to this "off-line" system!

On the other hand, many of us also use people that we know very well as references to gather information and make decisions about others. The GORB aims to leverge reliable professional references and personal opinions to provide a balanced and widely adopted "online" rating system, that allows us to gauge the reputations of one another.

What do you think?  Would you or your firm tell your clients about The Gorb and ask them for an anonymous review of your services?  Why or why not?  What are you afraid of?
