According to an article at Brandweek.com, the BzzAgent.com word of mouth marketing program will be eliminating rewards for many of its campaigns in 2007. They found that only about 13% of the points issued were being redeemed, so they began testing some campaigns that didn’t offer rewards, and according to BzzAgent rep Joe Chernov, they didn’t find a significant drop in participation. They say they’ll only be offering rewards for some campaigns in the coming years, and will be offering “social currency” instead — public acknowledgement, invitations to special advisory boards, etc.
