Referrals should be categorized by levels: Level 1-3

Level 1: know this person/business; they appear trustworthy and competent (now this type of referral would suck and none of us would like that type of referral, however, if we were honest with ourselves and to each other, 50-75% of our referrals fall in this category)

Level 2: I have a deeper relationship here and knowledge of the product/process; I would refer with a feeling of confidence 

Level 3: I have experienced this person and process; I have a high level of confidence in the people, product and/or process

All referrals are not created equally; it would be great to have some kind of qualifier.
