Spiffbox utilizes Facebook Connect and Twitter and is meant to build on top of pre-existing social networks instead of trying to build their own unique user base. Instead of trying to be another communication platform for you and your friends, it is intended to help you engage with people outside of your social graph. The focus here is on expert advice as well as career promotion and advancement.
In Spiffbox's system, the person sending a message or friend request has to spend points, which can be redeemed for cash, and the receiver gets points for responding. Users are given a set number of points when they sign up and can earn more by responding to messages, completing offers, or purchasing them. At this time, all of the actions on the site have a fixed cost, but Spiffbox is playing around with the idea of letting the sender define how much money they want to attach to a message. Obviously, if there is more money attached to a message, then the recipient will be more inclined to respond.
