Customized multimedia surveys are provided in a social network environment. A user that initiates the survey provides survey content and properties. The properties include criteria specifying which users are eligible to participate in the survey. Users eligible to participate can be identified by querying a database of user properties. The survey can include text, images, audio, video, and other media. Eligible users are invited and responses are received from those who agree to participate. Survey results are compiled from the responses received. Rewards may be provided to respondents. The reward may be provided in an ecommerce system that includes both redeemable and non-redeemable points. Cash can be converted to non-redeemable points. Redeemable can be converted to cash. A transaction may transfer redeemable points from a first user to a second user with points converted from non-redeemable points to redeemable points in limited circumstances. |
