Great advice everyone in any type of business, whether online or offline should remember. I think it's especially true when engaging in affiliate marketing. You can't just treat someone as if they were only a referral, customer number, or contract number. LIke you said, doesn't take but a second to say "hi. glad to meet you. thanks..."

Going one step further, everyone is a customer of someone at some point. The shop owner is also a customer of the company he purchases his supplies and tools from. So treat everyone the way you'd like to be treated. New and repeat business may be on the horizon.
