Fortunately for most successful companies, the majority of us love to share our opinions about the products we use, both good and bad -- for free!
It would be nice to get some bonus bucks or accessories in exchange for sharing our enthusiasm, but there are a couple of down sides as well. First, it adds to the cost of the product. Secondly, it tends to diminish the candor we convey as we would have a financial incentive to endorse a product. If two (or more) people pass out cards, who gets the credit and who keeps track? Who needs the bad feelings or the possible suspicion of lack of ingenuousness?
I often carry a few Hobie brochures to give to people who express an interest. I'll usually even let them try the boat out if they ask. So many people have generously shared their wisdom, opinions and product knowledge with me -- I'll be paying it back for a lifetime and still be in debt!
