In this post from his Duct Tape Marketing Blog, John Jantsch recommends that we should ask people to point out our mistakes and then reward them for doing it. According to Jantsch:

When you make this a policy and communicate it to the world you accomplish several things.

1) You get better or at least things get fixed. (Watch how fast your staff shapes up when they realize their every move in on notice.)

2) You admit you are human. Now more than ever people are looking for ways to connect with companies they do business with. Inviting them to participate in your customer service process is great way to connect.

3) You send the message that you care. You want to provide an absolutely perfect experience even if it means getting help from your clients to do it.

This idea isn't new among lawyers. Evan Schaefer at Notes from the (Legal) Underground has been offering a proofreading reward of $20 for each typographical error, $10 for each grammatical error, and $5 for each clever demonstration of how he can omit needless words.

Personally, I'm nervous about asking my clients to point out my mistakes, but perhaps that is why the idea is so intriguing.
