That ties in nicely with Referral Marketing.

People refer because they want to, not because they are being bribed to. If they feel they are being bribed, they won't refer.

There was a comparison done between 2 awards for people who referred and it was found that the more expensive and valuable award performed worse than the cheaper one.

This shows that people aren't interested in receiving a big prize for their referring efforts, but they do appreciate the recognition.

Interesting huh?
