Interesting to see Amazon rewarding their biggest advocates and influencers with real money.
Giving back to customers is certainly a good way of creating loyalty but will it make people sceptical of others peoples advocacy? Is Dave telling me how great this DVD is because he wants to make a cut from me? One would assume peer pressure and social values will persuade the average person that if they make good honest recommendations people will listen for a much longer time and maybe in greater numbers.
However It still only takes a few spammers and greedy tweeters to ruin the whole system for everybody...
